I had two PS3s - a 40gb I flipped and a 20gb that I still have. Full BC is the best way to go. When you are talking about hardware (20gb, 60gb) vs. software (80gb) PS2 emulation, give me full BC all the time.
I wish there was a 360 that did full BC - hence why I still have my Xbox.
Another good thing about BC and the PS3? You can create virtual memory cards and import all of your PS2 saves onto your PS3's hard drive. You'll have to buy an adapter - I got mine for $10 from Gamestop, even though you'll pretty much use it just once. I would also flip the standard Sixaxis controllers and get a new one with rumble too.
NPs on my end - and go full BC if you can find one.
