From november last year up to now, so far I've found for cheap :
1 XT pc with 2 other xt mobo
1 286 AT with its ega screen
A dozen of working socket 5/7 mobo and 2 p1 systems
2 slot 1 systems and 2 slot 1 mobos
A working 486 DX4 system (now upgraded to a 5x86) and a DX33 system, and 2 dead 486 systems
2 386SX25
A ton of 3Dfx cards
A ton of sound cards (including a boxed AWE64, a GUS and several sound blasters)
A ton of 5"1/4 disks and 3.5" hdds
A high end crt from 1997 that's extremely sharp.
And there are still many things missing to that list ...
For all of this, I've roughly paid from 300 to 400€.
And like I said, that's what I bought during a full year. To me, that was really worth it to wait more and get locally things I couldn't have bought normally on ebay because that would have been too expensive for me.
And the price I paid would become 0 quickly if I sold them on ebay, but I'm not going to do that
