DEFINITELY COME HERE. (And definitely don’t go to best buy.) I bought a Lenovo T-500 with Windows 7 Pro on it used from here about 3 months ago. I had several problems with the power supply, but I was running it on an inverter because I drive a truck over-the-road, (The inverter was bad) I’m only home in Phoenix a few days a month.The owner helped me over the phone (when I was in a Best Buy in Oregon), and in person a few times, he was very helpful. He also let me install 3 very important computer programs on the computer before buying, I didn’t think they would work, and was hanging on to Win XP, but I had to upgrade at this point. The programs worked, and I bought the computer. I’m very happy so far. The owner is a good person, and will help you out.
