I have a blackvue. IMHO, they are the best. Their software especially. Check out the various models on ebay and see which ones have the features you want. All video is backed by google map GPS breadcrumbing, and a tri axis accelerometer (admissible in court)...some have wifi so that you can live stream to your idevice, etc. I highly recommend one for all vehicles that you own. If it saves you from one BS ticket or BS accident, it paid for itself.
The image quality is also superb. Don't judge it by mine, since it was pitch black, my windshield was filthy, wet and it was blizzarding out. You can check out examples of video quality all over youtube.
