After hours of reading interesting threads on this forum, I know many things for sure like buying a Sony dru500 drive (sorry all you Pioneer-users

. Traxxdata would be the right disks to buy I think, but there is still one thing I just can't seem to sort out. It is my playstation and how to (re-)mod it.
I have a SCPH-30004 PAL version serial C 137xxx. 10 screws at the base, with a Neo mod installed. (I use Region-x to boot)
I want to play DVD backups of my games now, so I want a Messiah 2 mod chip. My question is: Is this mod ok for my PSX and what about that laser-thing I have been reading about. Will the DVD backups play smoothly or is my PSX or is it (the laser that is) 'too' old?
Since I still have to buy al of this stuff any help would be much appreciated.
