I know that this has been asked before, but how safe would you say it would be to buy a Mac off of eBay? I talked to my parents about it, but they were uneasy and they were afraid that when it came there might be something wrong with it or it would die a month later. What safeguards other than the $600 Paypal thing are there? How long does that last? Also, how good would a 1.0Ghz iBook w/ 512 RAM be for gaming? Would it work with Homeworld 2? What recommended games would work well on it?
