I've done well on the LEM swap, but have also had a few outlandish discussions.
When I was looking for some specific CRT monitors, one fellow told me that he wanted either $100 or $150 a piece on them depending on which ones(monitors others had offered me for free for shipping or if I would come and get them) and wouldn't even tell me where he was located.
Along those same lines, I drove up to Southern Indiana a while back and had a really nice visit with a guy from the LEM swap and bought several computers from him.
In any case, though, I like this idea. It's better than bouncing around PMs to people who might have parts when you're looking for something specific. BTW, I posted a WTB last night and Altemose spent about an hour looking because he thought he had one.
