I don't really see $800 worth of gear there. Most of it is old and/or cheap.
your not factoring in the fact that he probably has standard stock components in those boxes, you get two storage boxes.
You get a can of wd40. That's like 5$ so your already absorbing 0.6% of the total cost. There is a bench magnifier (50$), what looks like a HP8904A (100-200$), two chinese low grade power supplies (say 60$ each), can of duster (another 0.6%), old scope (50-100$), probes (20$), basic hand tool set (say 30-40$, more new, much less at a garage sale), Skil?brand drill and battery (50$ value used IMO unless its harbor freight.. maybe I am wrong here), big logic analyzer (say 50-100$ since it looks like one of those dime a dozen ones off ebay), a hair dryer (5-10$), scope cart (100$ is reasonable IMO), various spools of electronics grade wire (say 50$, they would be like 10$ each).
So thats like 750$ reasonable. Add the frequency counter, work bench, soldering stuff and solder, flux, etc..
It's not like a super steal of a deal but for a noobie that wants to get started and not be a eBay hustler I think its a OK deal. Even considering normal eBay prices.
Would I buy it? No, I would nickle and dime every fucking thing there over the a year.
If your not poor its a decent deal. I think the lab infrastructure is important because you can end up with some nice equipment working out of a tupperware otherwise, and work flow is extremely unpleasant.
Also the chair he is sitting on is worth something. 25-75$
And its supposedly all working. It has been burned in by use and you can be more sure of the components in the old stuff, vs a Ebay item that may have been powered up once for the picture in 50 years before the shady caps blew! This can save you alot of time and money and it adds value coming from a hobbyist. Does not really look like the type of guy that put together a bench just to sell it.
And those radios are wroth something. You can jump strait into doing HAM type stuff with them to learn radio electronics since you have good receivers.
And having a BUNCH of different supplies allows you to tackle more advanced circuits with isolated rails, bipolar rails, etc. Accuracy will suffer BUT you get capabilities to work on more advanced topologies. You don't sound like a volt nut or something to me...
It sounds good for your lab too because you seem to have a interest in digital systems/control circuits but have no analog gear. Those supplies and stuff are suitable for driving motors, remote sensors, etc. If that's all you have, then it sounds like that test bench would
greatly increase your capabilities.
