Video game/DVD collectors - Where do you trade your games online?
 

For over a year, I've been trading my video games online with other users instead of trading them into the store for peanuts. I mostly use gametz.com and cheapassgamer.com. I've also been selling games on ebay.com and half.com since around 1997, but some stuff really isn't worth listing for sale because you'll take a loss on it.

Lately, I've been trying out some of the new trading sites and was wondering if anyone has any to add.

Switchdiscs.com - Like peerflix.com only free, probably my favorite of the sites, just wish there were more users on there trading games.
Goozex.com - Charges $1.00 per trade
Gamershare.com - Free for beta, you get one free video game just for signing up (no credit card needed)
Barterbee.com - $1.00 per trade, you get one free video game just for signing up (no credit card needed)

Any other recommendations?
