I can see that there are whackos around and hope to avoid them. That's why I LOVE eBay. I have bought 2 lovely mac laptops with excellent service all round. I also bought an iMac 2 years ago and when it arrived the CD drive didn't work. i had paid with PayPal.The seller was furious and very hotheaded and didn't believe me. i told him I'd had it checked with a certified apple tech. After many harangues but only over a few days i used the dispute service on eBay and they froze his account. Now That's what saved the day! We finally settled, he gave me some money back and I bought and had installed a new drive. Then i looked in the old drive out of curiosity and a piece of paper fell out. Oh no! We were both right. I felt really badly for both of us. But I won't buy anywhere else because i feel I have protection. It doesn't prevent a hassle but I think it's a great way to get a great deal. But, yes indeed, keep all records!
