i use the gopro and as far as mounting options it is great.. not user friendly at all though.. editing of course is a pain in the ass.. i have a lot of video i just took at the dragon, etc. and i am way behind in editing.. here is a sample video i did - after launching the gopro at 40+mph onto the pavement and scratching the lens.. its surprisingly resilient..
