I have a 2 years old V3 ps2 and a 6 months old V9 ps2. I am just wondering does V9 have laser problem if install a modchip? I want to keep one for myself with modchip install. So, V3, V9 which is better? I heard V9 and above got problems too(over heating? or over current). Is there a modchip can 100% working on V9 without frying it?
