I use the fly6 and fly 12 from Cycliq. I have the latest versions and they work pretty well. I can't speak for the older versions, but they can be bought new or used pretty cheap right now. I rarely review the footage, but I can tell you that it will very clearly capture license plates with either the front or rear version of the camera. A few people have been hit in my area in the last year, one was a casualty. That was the deciding factor for me. I'm still going to ride my bike, so if someone hits me and runs, at least there is a good chance of catching them. Cheap insurance in my book. Every once in a while I catch something cool on camera, like a deer in the road that doesn't see me coming!
