Hi, I'm looking for a laptop for college, and I'm interested in purchasing an aluminum macbook pro. Not a unibody mbp, but the old one. I am trying to purchase one of these with at least a 2.1 GHz processor and 1 GB of RAM for around $700. I'm rather new to eBay, so if you have any tips I would love to hear them. Also, if there's any other method of purchasing older computers that people like, I'm interested. Thanks!
