Trading in 360 for ps3?

[Alex]

I'd say keep the Xbox, and just buy a PS3 when you get money to. It sounds like your brother would be pissed off if you sold it, and most games are multiplatform nowadays anyway. You probably won't get a good payoff from selling the 360 anyway. Gamestop rips you off, and I know I would never buy a used Xbox from eBay.
