The GoPro Hero, was their "first" generation Hero. IMO, it lacks the quality of the newer Hero's. I own both a Hero and Hero 3 Black Edition, and the quality that the Hero 3 produces is light years ahead of the original Hero. I have never owned a Hero 2, but I would say go for the Hero 3 Black Edition if you are serious about image quality and features such as 2K shooting. If you just want to mess around with it, go with the Hero 2 or Hero or Hero 3 White or Silver editions.
