Cooper is more expensive? I thought it was cheaper. I know how rock solid lutron is but it is a lot for a proccessor. I'm looking for a more affordable system. I have also been looking at the centralite rf stuff. At cost the switches are half the price of lutron and i can have the first ten switches for the price of an ra processor. I like the idea of spec-ing 4 or 5 switches without the large upfront costs of a processor.
