Look around and compare. The progressive isn't cheap. Ask me how I know. I bought 2. One 30A that I installed initially, and another 50A now since my trailer is getting converted to 50A. I found the 30A for $240 to the door. The 50A cost a bit more. That said there are charts out there that compare the progressive to the others. More protection, American made AND American supported. Only choice for me.
