I have a Macbook Pro 2.4 with 2gb of ram and the 8600 nvidia card w/256mb. It's a 17", and I really want something like a Macbook, since I just got a Mac Pro. It has a year left of Applecare as well. How much should I be asking on Craigslist for this? I want the money to at LEAST cover the cost of a decent Macbook.
