hate to be contraversial (cant spell) but IMHO its a bad idea ... as mainly a seller here i wouldtn want to be messign around .. also if you wanna buy something its better to know there is a seller selling it than putting it on the wanted section and hoping .. also in terms of time it would be slow and i dont really have the time to scroll throgh auctions looking for buyers....
maybe its a good idea in some cases butr should be limited to items not widely available such as art / dvds (soem are common but many hard to find) / games etc
DEFINATLY NOT COMPUTERS :shock:
