I found a 2008 MacBook aluminum unibody 2.4 GHz (the MB467LL/A model) on Craigslist for $400.00. Is that a decent price? Am looking for a cheap MacBook for my daughter and as long as it may work for another year or two, I'm thinking of buying it. Or do you think it's not work chancing it on a 4-5 year old machine? Thanks!
