Sounds crazy to me but whateverI'm not sure why he was willing to let it go for so cheap. I was lucky to have replied to the post first, because he still sold it to me despite way higher offers from other people.

After all, how often are you going to need that sort of performance? And if you do you'd likely be better off (financially) simply renting a scope of that performance when you need it.Dave.

On the top of the cart was a Leitz LaborLux binocular microscope. It had the eye pieces, bottom light, top (polarized) light, all 5 objectives (10X through 1000X), and a camera mount. Snagged it for $30 bucks. When my wife looked it up on online she nagged me for weeks to sell the thing. It brought in $1,600 on eBay, of which I used $300 to buy another microscope. $300 when into my "hobby" fund, and the rest went into the household accounts.As for that O-Scope, I'd sell it too ... after playing with it for a week or so. :-)

content: Quote from: allanw on November 11, 2010, 09:20:41 pmI ask again "how often are you going to need that sort of performance?" :->I could afford a scope like that if I really wanted to (and I'd love to), but there is no way in hell I'd ever bring myself to spend my own money to get one! Because deep down I know I simply will never need the performance.When I get something like this (and it's happened often actually), I always check out what I can get for it on ebay and then ask myself "If I had that amount of cash, would I hand it over to buy this exact thing?" If the answer is no, as it almost always is, then I sell it.You have maybe $6000-$7000 easy in your pocket right now, would you seriously buy this same scope with that money?I recon you could buy another scope almost as good for half the money you'd get for this one.Kinda reminds me of the contestants on Deal or No Deal who have "won" $20000 and then risk it with 50/50 odds to gain maybe an extra $10000. If you walked up to them on the street and offered then the same gamble, they'd laugh in your face. But at the time their minds think that $20000 is "play" money when they are on the show. Crazy stuff!I once had a top of the range Audio Precision Analyser in my home labhttp://ap.com/products/2700Awesome bit of kit, I loved it. But the value was simply too great to keep it, it was worth more than a new car.Dave.

It was only because I had a 400MHz analog scope that I was able to even see them. It'd be nice to have a digital version of it.I suppose I could sell it and get a $3000 300MHz scope or something, but there probably aren't any around.And the huge 10" screen and all the fancy waveform viewing features are so nice...Anyway as a college student I don't really need much in terms of spending money. The most expensive things I buy are to support the electronics hobby.

It will make you happy every time you look at it

content: Quote from: allanw on November 12, 2010, 12:51:23 amI've sold an Agilent 54621A 60MHz mixed signal scope for $2500 under 2 years ago. Had to list 3 or 4 times, but eventually someone bought it at the price I was asking. I thought that price was a tad overpriced for a 10 year old long discontinued 60MHz mono CRT scope. Albeit it was pretty nice.A matching buyer will almost always come along eventually, you just have to hold out.I'd be willing to bet it would go for well over $5K, you just have to be patient and possibly list a few times. Remember, you have a near current model scope here powered up very few times, there is a big niche market for this stuff.They key is to prove it's the real deal. Take *lots* if high res photos (hosted on your own server, no the shit ebay hosting). Show it fully working on all 4 channels, say it's "almost as new" show the number of times it's been powered up, offer inspection, link to the Tek site and ho much it costs new etc etc.Personally I would not list it for under $6K. Probably $7K with "Make an Offer" option.What taxes? Surely you woulsn't tell the tax department about this?, this is a private sale of a second hand item.Dave.

content: Some food for thought:This is a beautiful scope, worth far more and almost new.If the item is stolen, just if, the buyer faces civil charges from the owner and separate criminal charges.Unlike Craiglists which can be anonymous, eBay leaves an audit trail to control sale of stolen items, they are very good at it now.Given the scope is worth over $10K, if you get over $5K for it by US law it is no longer considered small claims, were few law enforcers care [ like trying to recover a lost laptop or cell phone.] If its sold on eBay, and the original owner wants it back, the secondary seller is now liable to both the original owner and the person he sold it too.The degree of the crime depends on what the original owner will value it as. Sale of stolen goods across state lines often elevates a misdemeanor into a felony.Any burden of proof that the buyer was not an accomplice to a crime rests with the buyer, and whether the law officers will bother to press charges for possession:http://criminal-law.freeadvice.com/white_collar_crimes/crime_property.htmhttp://definitions.uslegal.com/n/national-stolen-property-act-nspa/Most electronics are not investments, they are expenses.Investments appreciate over time, make you money.Expenses depreciate, lose money over time.If you sell a piece of high end gear that is no longer new, what you are getting is its residual value, its often less than the item bought new, for example if you bought a second hand HP 3458a, new about $10k sold by Agilent, it eBays for about $5k.Good luck!

There were a few times when it was invaluable, but also a lot of times I was just viewing periodic waveforms on two channels, with a simple edge trigger.I can't think of a time in hobby work when I really would need it. In fact, I quite like the challenge of working with equipment that's cheaper!

At lower memory depths the scope is more responsive and the digital phosphor updates really fast but obviously captures less info.The pan and zoom features are pretty useful but the knob is a little hard to use.

content: This week i had opportunity to play with Tektronix 4000 series.I was left disappointed may be because i saw Aglinet 7000 scope before it or just the sales man couldn't sale it for me.it has great performance ,low noise,big screen there no comparison with my rigol, but for $13k you get basic model without special triggersYou have to pay $1.5k for every type of trigger and communication decoding.the software felt fery simple not far from rigol without any special tests like Eye test .when i moved from my old analog scope to rigol ds1052 i felt like i got new swiss knife you could test and debug everything with it, there no such feeling when moving from $400 scope to $13k TekI am embedded engineer and maybe i don't see the great performance that analog engineer would see in this scope.My suggestion is to sell this scope and buy scope from less "NAME" company but that gives more advanced features like trigerring on and decoding serial busses.
