I recently went into a K-Mart and spotted an old model PSP for sale. It didn't have the box or any accesories, it is just the PSP. I charged it and turned it on and its running firmware 1.57 (maybe 1.47, I can't remember). I payed $110 for it, and its opened but never used. Its been sitting in a glass case at the K-Mart I went to for a long time. Did I get a good deal? and how about low official firmaware version?
