Gamestation are PISH! I remember when it was christmasy time when everyone was going nuts for the Wii, they were going to give me about £120 for my Wii console (BRAND NEW, UNOPENED..) so I sold it to someone I know for £210
Buuut I think i remember seein them give *about* £250 for a PS3 60gb
CEX may give you more. But you are best ebaying it, because most people here already have a ps3
