I'm looking for the cheapest of cheap tablets for a grandmother. Features and speed aren't exactly an issue. She plays really basic games, and I need to put a gigantic launcher (biglauncher) on it. The screen clarity/type/resolution doesn't matter at all. It has to be at least 7 inches, though, and it must be rooted/rootable. I've seen some $60 bargain bin tablets at walmart and on ebay (trying to avoid ebay though), but none that I could find any root methods for. I've considered some that were $80-$90, but I'm really aiming for as cheap as I can go. Any suggestions?
