My 80g, 4 usb, and B/C system died yesterday. Made some phone calls and researched the web. My problem and question is: do I replace with a refurbished one? Get a new one, money's kind of tight. Can't figure out why in checking retail sights why the 120g slim costs the same as the 160g slim? Or do I go to a pawn shop and get one slightly cheaper? Have bought a couple of systems from this one shop and had good luck with them. Are the warranty on a used one able to be put under warranty from Sony? I'm just not sure what's the best and most cost effect way to replace. Any help is very much appreciated. Thanks.
