It's been years since I've tinkered with a Mac, but with OS X being out for a while, and its stability improving, I'd like to try the Mac platform again. Problem is: As a PC guy, I've been dismayed at the high prices of Macs, even used/refurbished ones. I know they cost more than PCs because they are proprietary, but there is no decent power-user configuration under about $1,700-$2,000. Even used/refurbished G4s are selling for 90% of the new price, which makes it silly to even bother with them... So do I just bite the bullet and pay ~$2K to get one of these machines, or any other ideas on how I can snag a bargain???
