Video #498 ebay oscilloscopes
« on: July 25, 2013, 04:32:13 am »

Dave, Too funny! The Tektronix 2225 you pointed to at about 3:47 in the video is one of the ones I bought the other day. they had 4 of them and I had been hunting for a while since I watched your blog on the 2225 tweaking.? I haggled them down to $110 each plus $20 for shipping, and got two of the four they had. they showed up yesterday / Tuesday / seem to work fine. Came from some sort of Environmental lab in Indiana.

the one you pointed to was re-listed from that lot of 4.

also, love the blog, hope you liked the QSL card.

thanks.

There was a seller selling some Hitachi V-1065A 100MHz scopes for $105 shipped a week ago in "working" condition...I got one, it is pretty mangled on the left side and a couple buttons and the CH1 knob need cleaned internally but it works fine and the screen is nice and bright. Not a bad price for a unit with on-screen readouts, cursors, and a frequency counter... This model also auto-calibrates at power-on and does a pretty good job of it. Been waiting for a re-list as the seller posted they had 4 more, was thinking about getting more even though the rest are probably just as mangled.

I also got a V-1065 from the same seller for about the same price, same thing as above but without frequency readout, only a little banged up, mostly fine, had to clean two switches but that was easy and it works great (and isn't as beat up as the 1065A was).

But remember, most of these scopes are really starting to age. Both my 1065 and 1065A look really clean inside but switches and who knows when caps, dodes, microcontrollers or other parts will die. For some popular models (465/475), you'll find more dead / "untested" ones than good ones listed. Sometimes you can luck out, othertimes not :/ Good luck I guess...

One issue I have with Dave's video is that he really made it look easier than it is. eBay US is hot and it can be rough to get a deal, the patience and effort needed to score a deal more than doubles every year. It's really chance and luck at this point. Going for non-Tek scopes one stands a better chance though, he is right on that. Another issue is that he really made it seem like things are a better bargain than what they really were. Items he would say "didn't sell" for cheap were damaged items, like the 7100A that he noted didn't sell for $125. That item only has one working tested channel and no probes. Or the 7704a, which was cancelled because of an error in the listing... really, the $50 or less is a real stretch, even waiting and being patient.

I lol'd about "50Hz hum" on the US-listed scope

Not really, some of them were Buy It Now, still at reasonable prices.

Of course, that's always the case.
But if you set email watches, you get "lucky" more than the next guy.
I had an email alert for the Tek 2225 I wanted, and I waited about 6 months I think, but one popped up and I nabbed it cheap.

And many of them broken. Not to say there aren't scopes to be had for an okay price, but deals not nearly so much, at least on US eBay. Have to enjoy the hunt for it to be worth it.

Even when I was young and had no money, 6 months of time wasn't worth $40. And in the rapid world of electronics...

The entire point of the video was the shut up the whingers who say you can't get a cheap scope on ebay. You can, just do the work and learn how to search.
The video was not an exhaustive search, far from it.

I understand that so I'll shut up and stop whining now =)

I think the blog helped boost the price of the 2225 model.  they seem to sell at a premium over other Tektronix 22xx scopes,  consider that a complement.  ;D

I do believe that a cheap Chinese scope might still be better than an ancient analog. This Hantek is more than the older analogs, but probably will be more useful due to the storage capability and that fact that it is much newer.

I'm not saying we should kill all stupid people. I'm just saying that we should remove all product safety labels and let natural selection do its work.
