I am not sure where to post this, but I have a seller's question. I'm selling my Powerbook G4, and I am wondering if I am selling it for a reasonable price. Somebody already tried to undercut me once and I told them no. And no, I'm not advertising to sell it here. I'm only selling in my local area here in NYC. Anyway, it's a Powerbook G4 1GHz, 768MB RAM, 15" screen. It has a brand new motherboard, display and display cables, hard drive, lithium ion battery, and keyboard. It's quite honestly in like-new condition, as the ebay folk would say. I've always been very good to it, as it's been very good to me. I'm adding in a huge laptop case with it, as well. I'm kind of hating doing that because it's super handy, but I want to add incentive to those interested. So, my question, again. Is $550 too much to ask for for a powerbook in such condition?? Thanks again for your advice. Please don't take this post as an advertisement. I honestly just don't know how to properly sell an apple.
