I personally use three different PS1's: SCPH-10001, Net Yaroze, DTL-H1001. Of them I use the DTL-H1001 the most. It's region free, plays back-ups, and is a cool blue color. I also have a green debug PS1 that is non functional, so I can't give comments there. Speaking of chips, I buy mine from www.eurasia.nu for $4 with free shipping, though it takes a week to get here. If you can't handle the install, there are quite a few users here who could install it for you.
