Selling PS2 with extras!!!! advice please?

I have an original ps2 system that i am trying to sell. it comes with 2 controllers, two 8 mb memory cards, a dvd remote, guitar hero 1,2, and 3 with a wireless and a wired guitar, taiko drummaster game with drum, mlb 03, madden 02,04,06, and 08, ncaa 04, and 08, nba live 03, 05, and 06, namco museum, gran turismo 3, burnout 3 takedown, nfl street, and nba street 2, and includes all cables. i was wondering what a fair price for this lot would be and whether i should sell it on ebay, to someone personally, or trade it in to a store like gamestop. any advice is appreciated. thanks!
