Ok, so i bring my psp to school... Im coming home from school. Once i get home, i turn on my psp.. huge crack on the right side of the screen.. Im like **bleep** how did that get there.. I dont have a warranty anymore.. so im pretty much out of luck. Do you know if gamestop will buy it? Also im planning on selling a 128 MB mem stick, and all 3 of my games. How much could i get out of that? Im just wondering cause i want to buy a used psp... Also how much is a used psp?
