I just found a guy selling a turqoise ds (I don't mind the color) for 400kr(roughly 70USD). It comes with battery, adapter and stylus but nothing else. I already played on it for 15 minutes, and tried Phantom Hourglass and Pokemon Diamond. Both seemed to work flawlessly. What I would like is that someone told me all the things to check for before I decide wether to buy it or not. He said the reason he is selling is that he already has another one, which I also happened to notice. What also might be of interest is that I am at Dreamhack, the worlds biggest LAN and loads of people are selling stuff really cheap here. Any help is much appreciated.
