I have a Wii, used Wii games, and used Wii Accessories that I want to sell, or more like trade for a Xbox 360 and CoD: MW2. I have everything that was included originally except Wii Sports. Either give me a rough estimate or maybe a link that can help me OR if I can actually buy a used Xbox 360 Pro Refurbished/ Elite.

I think it might be useful if I listed what I have...

-System w/1 original Nintendo Wii Remote, Nunchuk, Sensor Bar, Console Stand, Video Cable, and AC Adapter
-3 Wii Remotes + Wii Jackets
-3 Wii Nunchuks
-2 Wii Classic Controllers (Not the Pros)
-2 Wii Wheels

Games:
Mario Kart Wii
Super Smash Bros. Brawl
Red Steel
Need For Speed: Carbon
Resident Evil 4 Wii Edition
Sega Superstar Tennis
Tony Hawk's Downhill Jam

Also do they still buy Gamecube accessories?

Thanks in advance.
But-But I like Gamestop. I'm subscribed to their GameInformer and own an Edge Card. Is there like a drive-to place?
