Iv'e never heard anything, good or bad. I understood you to say you checked with a local dealer. Residing in Northern Montana you should find a local dealer as your state is quite large, and service after the sale is ongoing.
I checked out the web site for bullfrog and they do have a really cool site! It's fun playing with the jet packs designing your own spa. Good luck let us know what you end up with.
