Looking to buy an xbox 360 off amazon sometime this week. There's a bunch of different versions, different built in hard drives, etc etc. What's the new xbox system have vs the old 360 version? How much of a hard drive do I want? I don't plan on downloading movies to it or many games for that matter. I have a ps3 that has a built in hd with 40gb and I've been more than fine for the last 2 years. I think the only game I downloaded to it was the arcade TMNT and some demos.

Find me some recommendations!
