...version should i get? Ok so i am looking to buy an Xbox 360 and i think there are like 3 versions out. the arcade the pro and the elite. I dont need the elite (even tho the black does look awesome), i dont think the arcade comes with a hardrive. But then that leaves the pro which is $300 which is kinda pricy. Idk what shud i do? Are there any other like in between models or something like that?
