put an ad in a free paper where you live.....i will bet $$ nobody on here is dumb enough to trade a ps3 (which is vastly superior to the wii) for a wii.....the visual quality alone isn't even comparable.
you're basically askign someone to trade a fuckin advanved game cube for a ps3/hd/dvd/bluray/cd player which also has hdmi (i dunno if the wii does, my boy said it doesn't but i do'nt care that's not the point)......
you should just donate that shit to charity for foster kids or something.
