200 dollars for an old Powerbook Ti is a good deal in my opinion. If you found one with a good screen and casing for under that I wouldn't second think purchasing it on the spot if you need it. Think about it, an LCD, casing, keyboard, possibly airport, HD, ram, optical drive, etc! There are so many components that could be reused.

I don't think that its possible to get one cheaper. I honestly think thats a good deal. Anyway, I will keep an eye out and let ya know, but I would say go with that.
