Hey guys, I'm about to buy a used Blackbook on craigslist. It's a 2Ghz, 1GB RAM, 120GB HDD version. He said there's nothing wrong with it except the battery doesn't hold a charge anymore. I can replace that for about $50. Our final price is $750. Is that decent for this model blackbook? I will most likely be replacing it with one of the new macbook pros when they debut, so resale value might be of importance (I may also up the RAM to 2GB for myself and for the resale). I've never ventured into the used macbook market, so I'm unsure about values. Also, is there a way to tell if a macbook is stolen? That does cross my mind when dealing with craigslist. Thanks in advance for the help.
