the breakers are expensive, that is the disadvantage. i don't know of any panel box like a home service for auto. personally, look up blue sea products on google or ebay, they have what you should use. its as close as you'll find, still fuses, but if you're blowing fuses a lot, there is a problem you shouuld fix. blue sea has fused distro centers that have a common ground feed, and a common power feed, then you can just run whatever power outputs to your switches and can have them fused for whatever you like.
