I'm interested to hear any responses to this. I've been thinking about getting one too, mostly for accident protection. I've read a little about them, but not enough to make a recommendation. Like most things, quality seems to be all over the place. I'd prefer one that records forward and rearward (the only way to provide positive proof in an accident).
Kevin, I have 2 GoPros. I'm only going to use one to watch my gauges during the runs, but I'll take them both. You're welcome to use one if you want. I have spare batteries and the camera can be charged through any standard power port or USB port. They're easy to use and download off of the micro SD card, which I have several 64 GB cards, but editing requires some sort of video editing software. I'm able to download the GoPro software since I'm a registered owner, and it's pretty simple to use. You might be able to find a free basic video editing software someplace on the web. Something to think about.
