Hi everyone here. i need all your opinion. a friend of mine is selling his Modded xbox 360 arcade version for rm400. i'm interested in it but it doesn't have a hard drive (since it's the arcade version). is it worth it? and for games like modern warfare, heavy rain etc do i need a hard drive to play it? the machine comes with 256mb for saved games by the way. i was thinking if i really need aa xbox hard drive i can get it from ebay for 20usd. what do u guys think about it? thanks in advance for the advice/replies!
