Bi-Directional Isolator

Has anybody used one of these bi-directional isolators in place of the more common solid-state isolators? I've read some good things about them on other MH websites.

The biggest advantage is that you can charge either house or coach batteries from either the alternator or the converter. Whichever battery needs charging gets charged. Since my coach battery tends to go flat if the MH sits for a while, and it's awkward to get to it with jumper cables, this is sounding very practical to me.

This system is not quite as cheap as it seems at first. The device in the link above is only a controller. You also have to buy the proper solenoid to handle battery current. Still, at $64 total, it's cheaper than a 100 amp solid-state isolator.
