Hi, we were debating on this too. xbox with the kinnect 4gb or the 250gb without. we decided to go with the kinnect. we got it at gamestop and the guy there said the 4gb is alot of memory and will have no problem with memory. The deal at
walmart with the 75 dollar card sounded good at first but you would have to still spent another75 dollars for the kenext, and they are sooo hard to find! and we also got a game with it. So hopefully we made the right choice. my DS are 14 and 11
