I have both the Playstation 3 (20gb) and the Nintendo Wii available. Both are unopened and come with the original receipts. I also have all the launch games available for both systems as well. I also have the 60gb PS3 version, but I'm still figuring out if I want to sell it or not.
The PS3 (20gb) is $1600 and includes an extra wireless controller and your choice of 1 game.
The Wii is $600 for just the system, all packaged contents (This includes Wii sports, 1 wii remote, 1 wii nunchuck) and your choice of 1 game. I have a copy of zelda if you want it.
