Got any suggestions for specific, inexpensive, used models?

Well, it's not as bad as it sounds: "unwiring" is simply pulling the 40
wires from the two sides of the socket; there's no desoldering
involved. The wires, however, do pass over the TIA which is why I have
to do it. I wish I had had two 20-conductor SIPP cables, instead of
having to cut a bunch of 18 AWG, but....

Nope. If I did, I probably wouldn't have to be sounding like an idiot
on the Stella list.
...a bit later...
AAARGH. Well, I'm relieved, but idiotic. While taking all the wires
from the socket, I realized that at some point the solder joint between
the jumper from the pin 20 (er, that'd be +5V) bus and the power bus had
given way.
With the TIA in place in the motherboard again, all is well.
I was simply not giving power to the TIA. D'OH.
