Considering a (used) PS2 slim
Back Story: I own a PS2 fat SCPH 50001 with a Messiah 2 mod chip. I am a bit concerned with the laser as it plays PS1 games and DVD-ROM PS2 games fine. It just has a hard time playing Blue back CD games and backups on Ridata DVD-R. I want to re-calibrate the laser, but my knowledge of doing that is somewhat limited and not sure how I can get the meter to help me adjust it.
Well I am considering a PS2 slim from the gamestop down the way with a decent laser on it. I was going to try craigslist but gamestop has the return policy so I'm probably gonna go with that if something goes wrong. I was wondering what series some users here suggest for models or versions. I've heard several of the slims have cooling problems and don't read certain games. My brother has a slim silver and it works great so I'm thinking it might be one of the silver models I want. Obviously I'm not gonna get the newer 900XX models for FMCB reasons. So my question, what models should I stay away from?
