I am trying to decide between the WFCO 8725 and the Parallax 6730 converter/chargers. The costs are about the same if you include breakers (the parallax comes with breakers, the WFCO does not). Which one is better in terms of reliability, ease of installation, and battery charging capability? I'm leaning towards the Parallax because it already has the breakers so that would be one less thing to do. Thanks.
