I have a three or four year old 15" MBP for sale:
Intel Core 2 Duo
2 Gigs of Ram
NVIDIA GeForce 8600M GT Vram 256MB
Removable Battery (recent upgrade)
Snow Lepoard 10.6.8
It's in nice shape and works like it should. I don't know what they are really worth with the matte screen, but I paid almost 3K when it was new. Does 600$ sound fair?
It comes with the original box and all the contents.
