Go for it man, the price of a dashcam is nothing compared to the money you will be paying for your insurance deductible or out of your own pockets let alone all the headache you will have trying to dispute a case.
I would recommend the CR500 HD, it uses 1/3 of the power compared to other cams (i.e. blackvues) required to run the unit (meaning parking mode will last 3x as long) and shoots in full HD. Not to mention the same GPS, G-sensor, parking mode, sony lens you would expect in a high-end dashcam.
Hope this helps
