Hi guys, I'm looking to buy a new PS3 in the next couple of days. Since I don't really want to pay retail price + tax, I'm looking towards getting it off eBay. I've seen PS3's going from all different prices on eBay, and some of the cheaper ones, no one is bidding on.... Is there something I should look for when I purchase my PS3? I know there are different size hard drives (80 gb, 160 gb, etc..), but is there anything else thats different between all the PS3's that are out? Anyone ever purchase one off eBay? Any advice would help me out.. THANKS!
