I may have struck up a deal with my wife allowing me to get a PS3 sooner rather than later. Now the problem is, which one should I get. I've seen some of the 80GB backwards compatible systems (which are no longer in production) available on eBay, but the big seller right now seems to be the 160GB system and the newest 80GB system. Since the 160GB is $100 more than the 80GB system, its not likely that I'd get that one, so now the question is, do I get a used backwards compatible system or a new 80GB system that won't be backwards compatible. I've got lots of PS One games, which is why I'm really interested in the backwards compatible one, so does anyone know if there is a big difference with other features of the newest system?
