Best low-cost Wireless Back-up Camera???

[Michael]

I just started using my enclosed trailer again (32' box with a 4.5' tongue), towing with my 9'10" camper on the truck. Needless to say, backing up is a crapshoot, and I have very little clearance between my fence and my house getting it into the backyard. Anyone have any recommendations (either one you liked or one to avoid) in wireless back-up cameras?

Thanks,
Michael

My experiance is that all wireless cams go bad eventually. The hardwired ones work best.
