I am looking at a 17-inch powerbook. It was on macrumors and the guy gave his ebay name. His name has been up since 1999 but he has no feedback. He says he bought the computer from someone else on macrumors. Another thing is he is a newbie. I emailed him and he sent me pics. Should I believe him or not. he is selling the computer 1,700 for for a 17 inch powerbook, and bluetooth keyboard and mouse.
