Warranty is a big issue with 360s. I've had 2 fail out of 3. My advice is to buy from amazon, if you're in the UK. Their customer support is SUPERB. They sent me a replacement 360 first, then gave me 30 days to ship mine back. Not only that but they paid for postage back to them. Granted, the postage costs are covered by law but a lot of retailers argue when you mention it
