Why dont you just give it into gamestop get the cash they give you im sure it will be more then eneough to buy a 10gig mp3 player..Dont go thru the troble of selling it online you can just go too ebgame, gamestop, and trade it in. Well i live in philly we have those stores here not sure if they have them where you live. Just an idea or try ebay dont just trade. You can get a 10gig mp3 player and some cash if you sell the psp instead of trading it/
