What brand/model Back up camera is the best?

I use my hitch (for a step) so I looked for an option - I have a Rosen camera mounted on my rear roof point down and out - it gives me a view behind the Beast and into the car behind. It has great angles of vision. I want to get another Rosen for my right side so that I can see the car on the right - potnetial good view into drive side Let me know if you want a picture on this thread.
