My local Mac store (not an Apple store) is branching into the used Mac business by offering to purchase used G4s and G3s. I happened to have my Rev. B 550 Mhz TiBook with 512 MB RAM, 30 GB HD, and a combo drive with me, and out of curiousity, I went to see how much it could fetch. The owner was a nice guy who floated a price range of about $800 - $1,000 for my machine, depending of its actual state. Now, I understand I could probably fetch $1,200 or so through eBay, I know that the guy has to make a profit somehow, so I wasn't too surprised he offered me a slightly lower-than-market price for my TiBook. Also, considering all the fraud and the hassles of selling online, I don't think selling it locally to the reseller is too bad of an idea. My TiBook is about a year old but has no Apple Care. I'm considering upgrading to a 1 Ghz 15-inch TiBook when it gets updated. How much do you guys think I could get for my current TiBook?
