A few things:
1. Bullfrog is a solid company that does mostly everything right.
2. That is a great price for a R7. I was quoted $10,600 for one (same things you are getting and my price doesn't include tax, either). So we're talking $11,000+.
3. For my price of $10,600, i looked elsewhere. I am able to get a really nice tub from Marquis or Artesian (still deciding) for MUCH less....like $2,000-$3,000 less. IMO, i would cross shop some and see what you like best. However, at that bullfrog price, it seems pretty on par with what other companies may cost you.
