helmet cam

Can anyone recommend a GoPro style camera and helmet mount? I just had a run in the other day on my commute home with a super aggro driver. I was thinking of getting something cost effective to mount on my helmet to document my trips to and from work... just in case. thanks in advanced. Andy

Years ago when I drove a car, I would often stop if it seemed I could be helpful. Unfortunately it was sometimes impossible due to traffic. Then when I started commuting by bus it was rare I could stop. Now that I ride a Radwagon, I do whatever pleases me at the time. My boss doesn't hassle me...
