And Boat Electric is in my own back yard (at least when home in Seattle!). I phoned them and verified they are not only a dealer but THE US distributor. They stock only a few parts like rail mount kits, otherwise their communicating with the folks in Australia. I'm thinking about placing an order for a pair of burner units just in case mine go bad. I'm betting that the lead time would be measured in months or quarters.
We're in Ventura now, Channel Islands tomorrow. I'm adjusting to endless summer just fine.
