yeah the older ps3 with all the ports I think was a 60gb model which you can probably pick up on ebay pretty cheap used...maybe even new...who knows.
I think the new ps3 slims might be backward compatible also but I am not sure, I personally think the older playstation 3's look way nicer also....they are shiny and have chrome and heat sensitive buttons and I just like them,there a good peice of electronic equipment to have handy
