I have a friend that is offering to sell me his Early 2008 MacBook 2.4Ghz 4GB ram 320 gb for $650. He is also including the original 160GB drive that came with the machine. I will most likely be able to talk him down in price, but not a ton more. Maybe $575? The problem is I currently already have a MacBook close in specs to his that I use as a main computer while not at home and I love it. Mine has .2 Ghz slower processor and is the Late 07 model. What should i do?
