Messiah or Origa?

[corey78]

Hello boys, I'm from Italy and I would like to put a mod to my Pal 30004R Ps2.. What chip is the best choice? I've read that Neo could cause problems with the laser calibration, so i don't wont to damage it. I think the best is the messiah (if i'm not wrong it let me boot without swap,right?) but what are the differences with the origa? I would know also if there's someone that could send me the chip in Italy, or better someone near Ravenna that could install it! Thanks!
