If PS2 BC isn't near and dear to you, just buy a new slim.
They use less power, they run a lot cooler and in the world of electronics, that usually means longer life and higher reliability.
Plus, I wasn't able to go 3-4 weeks without a PS3/BD player. My 60GB refurb is fine after about a year, but in all fairness, it sees even less use than my Xbox 360.
