Everyone is very paranoid about eBay but I've gotten 90% of my Macs there at a good price. If you pay through PayPal and do the whole thing through eBay you can't really get scammed. It's when you go outside of eBay to do transactions that scamming happens, and that's not eBay's fault, it's your own.
