As above, find one with a fixed GPU, either a 3,1 or a 4,1.
I've got 2 3,1s (A1226) with the GPU fixed, and after you stick an SSD in them and max the ram out they are great general use machines with El Cap on, and can run later OS acceptably with dosdudes patches, or they are lightening quick in Snow Leopard if you want to go that route.
I've also got a 2,1 (A1211) (with the less failure prone ATI chip) which I've retrofitted an LED screen assembly from a 4,1 (A1260) into, it's a bit of a fiddly conversion process but the result is worth is as the LED panels are much brighter.
All of the above are using the matte screens though, I'm really not a fan of the glossy MBP screens, far too reflective for use anywhere with any amount of light!
I've got (and had) a few PB G4s as well and I like them for different reasons, but the screens are nowhere near as nice as even the CCFL lit MBPs.
