A few days ago I purchased a used PlayStation three with custom firmware on it. I could not see it at the time but now that I have the system in my room where the lighting is better I realize that the system looks sort of dirty and has several scratches across the top. Also, the guy told me when he brought the PlayStation three over they had a lens issue and the lands issue had to be repaired. I know it is impossible to say for sure but, I'm wondering if I made a bad deal. Are the PS3 is generally as problematic as the Xboxes have been? Is the lens issue something that is likely to be a reoccurring?
