content: I can get this used directly from Tek (I happen to work by them).In good shape overall and everything appears to work as it should. The only thing the tech noticed was a bit of rolloff when measuring the square wave off the probe calibration point. The tops of the square weren't perfectly horizontal. He thought a new cap on the input would likely fix it.I haven't seen anything cheaper locally nor on eBay once I through in shipping.Sent from my SM-G930V using Tapatalk

content: Welcome to forum.That seems a lot for a 50 MHz scope unless it carries some warranty and comes a manual and complete and original probes.Typically old scopes are valued at just $1/MHz.

content: I paid $125 shipped for mine a couple years ago on ebay. It was in very nice condition and came with a 30 day return option. Dave made that scope a bit more popular/costly by running a two video series on it. If you like the scope, and you know it's history and what condition it is in I don't think it's too high, particularly if there is no shipping. Mine turned up with a wonky pot on the horizontal fine tune. I could have lived with it, but Q Service had a replacement board from a late model donor that I picked up for $45. Now the machine is perfect and I really like it. I have a 475 as well, but for simple things the 2225 is quicker. All of the manuals are available either free or for a small fee.

content: 2225 goes for a lot because it has a 5mV/div + 10x vertical zoom function. This seems to attract audio nuts for some reason. Unless you need that, I'd find another scope.Also the x50 zoom is horrid. 2215 is much nicer and probably cheaper.I buy up all the cheap 2225's as they appear in the UK as you can make £100 with some turd polish

content: I have a 2213a and a 2215 I much prefer the 453 over both of them. If I were in the market for a "new" affordable 100% analog scope I personally would look for a 400 series. Unless weight was one of my top priorities.

content: Agreed. 465B is the best of the lot IMHO.

content: Thanks for all the input.I thought $150 was a bit high, but considering it's from Tek (the Vintage Tek museum), I thought that might add to the value.I'll go back and see if they will through in some probes and then make a decision.

I didn't mean the the scope itself would be more valuable, just that there might be value from the "you know it works" standpoint.I haven't found any scopes that I can have delivered to my door for $150 that are guaranteed to work.Might have to just wait a but more.Sent from my SM-G930V using Tapatalk

content: you're going to have to hunt hard. I feel they're getting rarer and rarer (the good scopes). I paid 250$ USD for my 2465 4 years ago, shipped and fully working.You can still easily find the low end analog scopes, but maybe not at a decent price.

content: I live in the same area (west side of Portland). Coincidentally, the only Rigol office in North American is in the same city as Tek.I need to visit the Tek museum again, haven't been there since they opened a few years ago at the old location.Took this photo the first week after the museum opened in September 2011.

content: Quote from: SteveOregon on July 21, 2018, 02:57:32 pmI just looked at the Portland Oregon Craigslist. Glad I dont live there I would be so poor. On my local Arizona Craigslist sometimes its months between postings of worthwhile scopes or test equipment. There is a 2432 in Sammamish that fits the $150 OP right now. Most all others are "refurbished" and out of that price range. Unless he wants something other than a Tek.

content: eBay has a 2213a right now for $114, incl. shipping that is "tested and functions correctly," a 2235 that passed basic tests with.a square wave for $185 shipped, and another 2213 that is "guaranteed to work" currently going for $20 plus $40 for shipping.My reading tells me the 2213 is a better scope from a quality standpoint (made in the US), so I'll watch that auction and make a bid near the end if the price is in my budget. I could stretch a bit for the 2235 as well, so that's my 2nd choice.I'm going to drop by the museum again and ask their advice on these models.I'll post back when I've made a decision.Thanks for all the input.

content: With the 2213 non A make sure the SUP3010 was done. I would stay away from the non A versions of the 2213 and 2215 unless you are sure that the CRT is nice and bright (my opinion only). 2213A does not have a standard delayed time base, if thats important to you. It has a delay time switch and a multiplier pot. Other than that its a nice scope.

content: Dropped by Vintage Tek and talked to the guys there about my options, and after talking for about 30 minutes, one of the techs there said they had a 2246 100mhz 4 channel scope he would let me have for $150. They had just finished going through it and repair one fault they found. It could use some more cleaning, but for the price, I couldn't pass it up. Plus they said if I had any questions or problems with it to just drop by.I want to thank you all again for the input. I learned about the options out there and feel Imgot a better deal in the end for having the discussion.James
