I am going to get my first ever PS3 console as i wanted to hack it to play all the homebrew on it.

I was wondering are the slims better than the fat PS3's ?

Is there anything I should watch out for when buying a PS3 ?

Personally id go with a backwards compatible 60gb ps3, it has all the bells and whistles memory card reader 4 front usb ps2 chip single lens bluray shinny chrome bits , in my eyes the 60gb was/is the best one silly how sony took all that coll stuff out
1 thing to look for is that it cant be over firmware 3.56 atm as it is unhackable mine had 3.55 and i installed cfw on it it was the best
Hope this helped
