Whats the best chip for a V3 PAL PS2 ?

[DC_Jay]

i got my ps2 on the first day of the pal launch.its model number is
30003
and it has an all metal expansion bay so it looks to me like a v3.

after reading charlie's posts it seems the messiah is a bitch to install in a v3 when it comes to the laser.would an Origa be my best option?.i just want to be able to play cdr backups(including 80min rips)and DVDr backups.i already have an Action Replay v2.

i know the Origa can boot originil imports but i heard it wont boot some(DMC & Silent Hill 2 us).so where do i stand?.
