After several weeks of comparing many different models and manufacturers, we finally decided on a hot tub from Bullfrog Spas. Their web site is www.bullfrogspas.com.
We chose this particular tub mainly because of its design. The tub itself has interchangeable jetpacks. What this means is that if you don't like the configuration of the jets, you can change them without replacing the tub. You can also keep a couple of extra jetpack configurations on hand to add a little variety to your hot tub experience. Because the jetpacks are removable, the plumbing throughout the tub is simplified. Water is supplied to the jets by a main line, which runs around the perimeter of the tub. This greatly reduces the number of hoses running around the tub thus allowing more room for insulation. The tub itself is well insulated. Every void is filled with foam.
