I have a question. I've been looking around online about the PS3s and what would be the differences among the PS3s other than price and HD space. I can't seem to find it anywhere.

Thanks, this is highly appreciated.

That is pretty much it. The 80GB version comes with a game.

20 gig (no longer in production) = no wi-fi, no card ports
60 gig = 40 gigs more space than the 20, wi-fi enabled, card ports
80 gig = 20 gigs more space than the 60, wi-fi enabled, card ports, Motorstorm game, NO emotion engine - for playing PS2 games, this is now handled via software emulation vs hardware

Hope this helps.

I bought the 80 gig from costco which included motostorm, extra remote and a blu ray remote. I dont care about ps1 or ps2 games so it was a good fit for me
