Thanks for those suggestions. I like the look of CoinGig and the escrow aspect of it. Will give it a shot.

Bitcoinclassifieds isn't really an auction site; and there's nothing really to differentiate it from other classifieds, so far as I can tell

CoinPost looks nice, but seems to have few listings on it. It's the ol catch-22: without listings, you can't get buyers; but without buyers, you won't get more listings.
