Who makes THE best rear view camera??

[King]

I have the NAV-TV camera which is color and reverse image. Works well ..I have had it for about a year now. The plastic chrome trim ring is now peeling off and the lens are dirty on the inside. Looks like condensation on the inside as well. The image is just not the greatest in terms of clarity.

A friend of mine has the new lexus truck, and the clarity of his backup cam just blew me away. I believe it's just the factory camera. They probably use a better LUX camera...

Anyone know of a better camera for the same job? I know there are all sorts of cam's available now including infra-red night vision. Where's the best place to get one??
