Joe,
Try Alternative Energy Engineering.  A Battery Selection Switch you are
looking for is at
http://www.alt-energy.com/catalog/switches.html
 I've used them to purchase a Dual Battery Relay 6 months ago.  They
shipped the next day and included a real cool catalog.  Unfortunately I
have not installed the relay yet.
Also look at West Marine, I think they have battery selection switches.
