The lights are on
First and foremost, before buying a ps3 slim, try to find an old 60 gb model. It has more USB ports, which I use all 4 of mine, and from what I've heard, the new ps3 isn't backwards compatible which there are a lot of ps2 rpgs you probably want to check out. Don't worry too much about the smaller hard drive because sony was smart enough to make it easy to put bigger hdd's in. My 60 gig ps3 is running with a 500gb hdd right now. As for PS3 RPG's, Cross Edge is a really good one, Disgaea 3 is so-so, and FFXIII is just over the horizon.
