Do you have any rules of thumb for how much those oldies are worth? In
my little corner of the world, the accepted rule seems to be "Pay
anything they ask and outbid everyone if you can, no matter what it is
or what condition it's in." The end result is that anything used is
gone just about immediately, for more than that same model would cost
new, sometimes ridiculously more. Lots more money than common sense in
these parts.

I like having old stuff. I can't afford what it costs around here, even
when I can find it.
