Just a little heads up. If you can find this used at Gamestop buy it there. Take it home and install it on your Xbox. Then return it. That's what I did. Once you've installed it you never need that disc again. I even installed it on a couple of friends Xboxs while I had it. When I went to return it the guy at Gamestop said, "I would've done the same thing." So they don't even care if you do.
