Replying to camera for helmet cams???

i have a gl2. it is very expensive. i don't want to break. i'm considering getting a smaller, lighter and less expensive camera for a helmet cam. that way, next time i botch my bio on cardiac cave, i wont break my gl2. for those of you who have experience using helmet cams, what kind of cameras do you use. should i just fix up some super padding and shove my gl2 in a back pack? or would you recommend buying something smaller?
