I've heard for years that there's some model of PS1 that's worth a lot of money, something about the quality of the laser used in the disc drive? I think it's the very first model which would have a date of 1995 underneath, and they're pretty hard to find since they didn't sell too many at first. I always check when I see a PS1 at the thrift stores, although I rarely see a model earlier than 1998, although I did see a 1996 once. Can anyone shed some light on this for me?
