Old analog scopes are not worth it at any price. There will be a bunch of people that like "warm analog feel" but as far as actually being useful for the purpose, they all suck. Unless you want to look as sine waves and not much else.
LOL. I looked at the specs, it has 1 MHz bandwidth. Really, $20 oscilloscope kit from ebay will have better performance that this thing. EDIT: It looks like the actual bandwidth is 20 MHz. Still not worth it.
Don't bother. The dud should be paying you to haul his garbage.
