New category for trades?

I will gladly trade my soul to anyone who can offer in return the steady knowledge of when to hold 'em, when to fold 'em, when to...
seriously, though, trades are a great idea, and the 3rd party / escrow thing works just as well for that as it does for any other transaction (i.e. a pain in either case, but probably worthwhile).

There are many such possibilities, especially, as bmpnyc points out, when someone has multiple systems. I, for instance, just upgraded to a much better cd/dvd transport, and now have relatively cheaper cd and dvd players I don't need. I bet someone who wants to start a secondary system has some good cable they aren't using that I now need.
