Hi
See my post about eastgerman meter for $6
Commie gear is almost free at Europe now
You would be pretty badly mistaken, lot of that gear are collector items (especially if it is working). Also finding something in good working order is like searching for a needle in a haystack. Most of that stuff has been thrown out after the 1990 when better hardware became available. In addition, do keep in mind that depending where you are, the postage on these items alone could be more than your $50 budget - e.g. the East German meter weighs 4kg. Sending that e.g. to the US would be really expensive. Oh and it won't work on 110-120V neither, no such BS in the former Soviet bloc, we had everything designed for 220V only ...
Also good luck trying to find components if something breaks in it - keep in mind that we didn't have access to western components. So what you are going to find inside are obscure "commie" parts, in the best case straight clones of the western ones (e.g. 7400 logic), in the worst case a custom Russian-made chip that is a complete unobtanium. I have found a schematic of this meter online and it seems to be a mix - 7400 logic + obscure, specific parts, such as the main IC controlling the entire meter.
Nobody serious is going to recommend you a meter like this, even less so because most people here aren't familiar with this gear.
