Dave shows you how it's not that hard to find that mythical $50 analog oscilloscope on ebay. At least in the US and UK.

I've been trying to get one since I saw that first video.

Here in Brazil, the closest I got was a 15 MHz Tektronix 922, for around $200. I'll keep trying, anyway...

Yes, as Dave said, not going to work everywhere. I am sure that here in Chile it would be almost impossible. If I did find something here I would not pay a cent for it until I saw it working. Used here usually means totally worn out and not worth anything.

I got an 3 channel 100 Mhz LBO-516 few weeks ago for 19.99 (+ 25$ shipping) .. it was dinged badly on one side and not really working. But I said that the worst risk is one week without Starbucks so ... got it in, and the only fix I had to do has involved a hammer :) - simply the outer case was bent and it was shorting a board. After the required banging and cleanup i have an really nice scope ... The only problem is that now I am feeling guilty to spend 10-15$ on some probes.

I agree iith you guys, in US is easier to get this kind of smoking deals .. with a bit of luck of course and risks.

In case u wanna see it .. here .. http://www.ebay.com/itm/Leader-LBO-516-100Mhz-3-Channel-Analog-Oscilloscope-/161036150846?

So it was pretty bent .. but once i got it straight again i have an 100 Mhz scope  :-+

On Ebay Aust,Imperial Foxonline,& Industrial Surplus Australia make a habit of asking ludicrous prices for Oscilloscopes.

The former had a BWD 880 High Voltage 'scope for around $600 which is a reasonable price for a specialist instrument of that kind,but in their next ad they were asking $350 for a BWD 502 6MHz single channel thing,which is worth about $5.

The thinking seems to be: "They're both oscilloscopes,right?"
The unfortunate thing is that others see these prices & think these things are worth that much.

There's a HP 180A on at the moment with an opening price of $50 & no bids.

It is shown with both traces on,but apparently they "become dim" after a couple of hours.
Maybe worthwhile,as they are a nice instrument.

There is a lot of surplus oscilloscopes in countries with a large electronics industry. If your country doesn't belong to that group, e.g. because the local electronics industry died before transistors became really popular, you are out of luck.

Locally we have high prices, and it is actually a group of surplus vendors who are very busy trying to keep it that way.  They have started to always put a bid in when a brand instrument comes up on ebay locally. A bid high enough to annoy/distract normal buyers. They regularly end up as the winning bidders, but they don't seem to mind as long as they keep market prices high. They'll list them on their own websites with a surcharge for "calibration", warranty, etc. or use them for parts.

I have no idea how long they will able to do that and if they actually lose a lot of money or if it works for them.

I suspect that won't last, mostly a question of educating the potential buyers about the alternatives. You can get a brand new Rigol for about $350, which means that for most people the real value of a decades old 'low' BW analog scope is far below this figure. However, this does require beginners know about the other options.

As for more recent medium cost models, then I don't understand what is going on. When the resellers ask more for a 10+ year old DSO than a comparable new model cost, then something is up. Yet I would assume potential buyers for these models would be sufficiently well educated to know about their options.

For instance I have been keeping an eye out for a better scope for my home lab for a bit, just to consider my options. While I could occasionally use 4-500MHz bandwidth, maybe from an old scope, I also have to consider that the list price of a brand new 200MHz DSOX-3024A is about $4700. This comes with a 5 year warranty, says 'Agilent' on the front and is VAT/tax deductible. That makes paying several thousand for a 10 year old dual channel instrument, perhaps even without a proper VAT receipt, a complete no-go. ::)

The US may soon have a glut of used test equipment on auction sites.  The budget sequestration is going to cut pretty hard into the defense portion of the budget. 

This will likely ripple down to defense contractors and they will need to tighten their belts.  Some of these guys have been on the gravy train for so long that they likely have excess equipment (not to mention employees) that they'll send packing.

Dim screens are one of the banes of used CRT equipment.  I don't bid on units where the screen photos are obviously taken in the dark, like that first Hitachi.

I've spent probably $35k on eBay in the last few years, averaging about 3 cents on the dollar compared with list price.   (My faves are my Tek 11801C and TDS694C.)

Dim screens are a problem.--The brightest CRTs I've seen are on the BWD 'scopes,but they have other problems,like triggering faults on the older 500 series.

The HP 180A which I saw on EBay Aust apparently has a fault,causing the display to dim after a few hours.
That is not normally due to a low emission CRT,so it might be worthwhile.
I've seen a few Spectrum Analyser plugins for the 180A over the years,but mainframes are rare.

The problem with defense related stuff is that they have changed the sales method. In the past you could go to the actual military base and it was auctioned off that day, you paid cash and took stuff home. Now the process is done by govliquidation.com and they often don't  allow bids below $50, also frequented by the large used equipment resellers that can afford to spend $200 on a chance you make $500 .  Really a shame they changed the way sales are done.
