This always makes me laugh a little bit, when a local thrift store sells an older Mac for outrageous prices. Today, I found this 20 inch iMac G4, 1.25 GHz, 768 MB RAM, 80 GB HD. It had the original white (granted, yellow) keyboard and mouse, and Pro Speakers, too. Overall not a bad iMac. However, the price made me laugh for a few minutes. $400?? Come on. Not even on a half-price day would I (or any person knowledgable about older Macs) pay that for it!
