I agree with above-I've bought TONS of stuff from these guys and the last Prodigy I bought, they were the cheapest I could find. The P2 is linked there it looks like but the standard version is what I have for my current trailer I'm working on. It's plenty for this and was under $100. They do a good job and have excellent customer service from my experiences.Beau Bo said:http://www.etrailer.com/dept-pg-Brake_Controller.aspx
