Get a cheap Japanese PS2. The PS1 console laser doesn't last long.
I've bought from here before:

The chips are cheap and work great. Shipping from China takes a while though.
The chip I linked to works on the psone, but it's a little more difficult since the solder points are super tiny and you need to use 30 awg wire which sucks all the balls.swapdisk? I've got one of those itty bitty ones and when I checked (long ago) it was my only choice.
