Just go for it!
The Xbox 360 is a smashing console.
Ridiculously good value for money and no matter what anyone says, xbox live is fantastic and well worth the mere 39.99 a YEAR!
Many people say they break down a lot etc which just isn't the case, mine has broken down once in three years, and I had it returned for repair and sent back to me in a matter of 4 days which is nothing. If you're thinking about buying this console, DO IT, you won't regret it :) It's a remarkably good purchase, no wait - INVESTMENT!
