content: I can buy a DS1054Z scope locally on craigslist - what would be a good value for a used model? Depending on included probes etc...How can i best test it? I do have a low power digital signal generator available...

content: Well, you can buy a new one from tequipment for $328, so it would have to be less than thatYou can test it well enough with just the probe calibrator.

content: From what I've seen on ebay, used Rigols sell for as as much or more than a brand new one, doesn't make a lot of sense to me but I guess some people are not aware of Tequipment. I think they're so cheap to begin with that there isn't much room for the price to drop.

content: I would offer $250. I think an easy cash transaction compares favorably with of the hassle of creating an ebay auction, packing and shipping it, dealing with a potential problematic buyer, the ebay fees, waiting for your money...$200 is too little; $300 is too close to a brand-new unit.While you're checking it out see if it has been hacked already. It's easy to do yourself, but it's a small bonus if it's already been done.

content: I believe that the price of a used good should be at most 60% of the new one.. So $200

content: That sounds reasonable to me, but from what I've seen they sell for more than that. I haven't really been looking for them but I did see two different used ones sell on ebay for *more* than the cost of a brand new one from Tequipment. Like it or not, ebay sales pretty much set the value, although ebay takes about a 20% cut so that must be accounted for.

content: Something that weighed heavily in my last scope purchase decision:Buying new from TEquipment meantnosales tax, free shipping directly to my door,andit came with a three year warranty.Peace of mind is worth something too for some people. Just saying...

content: I miss the days of no sales tax on online purchases, my state requires online sellers to collect tax now. Technically you were supposed to pay the tax before too but I've never heard of anyone actually doing that.

content: My experience with the people who advertise on Craigslist has been this: They buy things from China brand new at discount and want to sell them for a profit, so you will not be saving much over buying direct from China and waiting for you package.

content: Quote from: james_s on April 14, 2021, 12:09:28 amAre they selling for that...Or are they just listed for that? In my experience, people selling their "like new" equipment are unrealistic dopes. I've seen it in so many areas too.You have to ask yourself...Do I really know how they treated it? AND...A question which has a definite answer...Will the seller give the same warranty as the retailer?....NO.Given that a brand new unit, as mentioned, sells for $328 I wouldn't pay more than $150 for a used one in excellent condition. A brand new one is BRAND NEW, never used, and comes with a warranty.

content: Quote from: MauriceS on April 13, 2021, 11:58:16 pmI'd say $250 for areally niceone.Quote from: MauriceS on April 13, 2021, 11:58:16 pmJust connect all four channels to the nearest mains socket, make sure the sine wave is clearly visible on each one.No, wait, you're supposed to connect the probes to the calibration signal and make sure it's 1kHz and approx 3V.Quote from: MikeK on April 14, 2021, 01:31:24 pmYep. Worry much less about the 'scope and a lot more about the previous owner. Are they the sort who used it with Arduinos or are they the sort who'd do the "Mains Socket Test" the same minute they unboxed it?Check if all the little spring things and accessories are present and correct, not because they're valuable but because they show that the owner cared.Original packaging is also a sure sign that the owner is the sort of person you should be buying from.Car analogy: Look at the paperwork and service historybeforeyou start the engine and take it for a test drive.

content: Quote from: MikeK on April 14, 2021, 01:31:24 pmSelling for that, these were auctions and the price got bid up over what a brand new one would have cost.Ebay makes it really annoying to try to look at sold listings now so you'll probably have to jump through some hoops to actually see them but here's one that sold for $305 + $35 shipping, so $340.https://www.ebay.com/itm/RIGOL-DS1054Z-4-Channel-Digital-Oscilloscope-Excellent-Condition-/174711392548?This one sold for $309 + $57.15 shipping so $366.https://www.ebay.com/itm/Rigol-DS1054Z-Digital-Oscilloscope-4-channel-UPGRADED-SOFTWARE-100-MHz-/373481981349Here's one that sold for $287 + $41.45 shipping, so $328.https://www.ebay.com/itm/RIGOL-DS1054Z-4-Channel-Digital-Oscilloscope-Four-Probes-All-Options-100MHz-/143972078139$265 + $19.60 shipping so $284https://www.ebay.com/itm/RIGOL-DS1054Z-4-Channel-Digital-Oscilloscope-Excellent-/1147111324615 sold at $470?!?https://www.ebay.com/itm/Rigol-DS1054Z-50-Mhz-4-Channel-Digital-Oscilloscope-WE-EXPORT/282412250159This is the cheapest one I found, listed at $200, best offer was accepted, so we don't know what the actual selling price was but it was under $200, plus $41.45 shipping.https://www.ebay.com/itm/RIGOL-DS1054Z-4-Channel-Digital-Oscilloscope-/353365434178Doesn't make sense to me and with possible exception of that last one none of these strike me as any sort of bargain but that's what happened. Never hurts to offer a price you think is reasonable though, the worst that can happen is they say no and you can always go out and order a brand new one. Personally having seen what they tend to sell for on ebay I see little reason to play that game, it's easier to just order a new one from Tequipment.

content: And if you don't specifically have to have a DS1054Z, don't forget that you can get a GW Instek GDS-1054B, arguably a better scope, for only $292 new.

content: From what I've seen the used oscilloscope market is nuts right now for whatever reason, covid driven boredom driving up demand I guess. Like forget finding the $50 20+ MHz 2 channel analog scopes that used to be easy to score, nevermind a used DSO at a reasonable price.

content: Quote from: nctnico on April 14, 2021, 10:25:19 pmProbably could, but honestly I think if I wanted to find a side gig to pay for a Rigol scope, I'd be better off taking a job at McDonalds or something for a week or so. Selling on ebay and dealing with idiots and shipping and all that is a lot of work and not very much fun.

content: I have bought second hand equipment but I sure don't recommend it. When you figure out how much to offer, see how far away it is from the brand new, with warranty, price.I just don't trust users, I have no idea how badly they have abused the equipment.From what I see on eBay, the used price is just about the same as the new price. That's good news is I ever want to upgrade.

content: I buy pretty much exclusively secondhand equipment, it has worked out very well for me, but I like older formerly high end stuff, I don't own any Chinese gear other than stuff like the little $20 component tester and other small gadgets. I don't depend on it to make a living though, I do use my gear but for the most part I think I get more enjoyment out of bringing a neglected instrument back up to snuff and collecting interesting gear that I dreamed about owning back in the day but could never have afforded when it was new.If a person just wants a modestly priced scope to use, doesn't need more than about 100-200MHz and doesn't want to tinker with it, it's hard to go wrong with something like a Rigol, Siglent or other new budget instrument.
