my friend is selling me his PS3 Phat for $130/180 [don't really remember]. should i jump on the deal and get it ? what kind of issues are there to expect between the Phat and the Slim ? he hardly used it first of all and he is also throwing in 2 controllers and possibly some games he has for PS3 [i know he has MW2 for sure]. can i play games from Japan on it ? if so , that'd be great !
