My friend is selling his iMac and I am thinking of buying it but am not sure about the price. While I want to give him a fair price at the same time I don't want to be ripped off either. The computer specs are: iMac 24" Intel Core 2 Duo (2.16GHZ), 2GB SDRAM, 250GB HD, NVIDIA GeForce 7600 GT Video Card 256MB, dual layer DVD-R burner. Apple Care until end of 2009. He wants around $1200 for it, is that reasonable or too much?
