How much should I sell my PSP for?

I have a PSP-1000, a 1GB Memory Stick, NBA 07, Madden 07, MLB 07 The Show, ATV Off Road Fury Blazin' Trails, The Benchwarmers UMD, Talladega Nights UMD, and Lords of Dogtown UMD. How much should I try to sell this for? Also, it is possible for me to jailbreak the PSP for free games if that would increase the value. How much do you think this is worth and where should I try to sell it? The PSP is in near perfect condition, too, along with the games and movies.
