I was gonna get the 4gb but i realised for like £40 more you can get the 250gb so I did... When I got the 3year warranty & HDMI Cable it came to £300+ (can't remember the exact total) & this was the new xbox (got it almost two months ago) so I'd recommend payin' a lil extra for more gb's might also work out cheaper than buying an external hard-drive...

also when my mum went in the store... they said that the stuff they have online diffur to what they have in store so it's better to go in store
