Im trying to get my ps2 modded in order to play back-ups from original copies and downloaded copies. Im not an experienced solderer so I need a pro to install for me. A guy close by is willing to install a modbo 745 3.0 for $100. First question is am I getting ripped off? Second is whats the difference between getting a modbo chip to a good quality chip like the matrix infinity. Thanks for any help.
