Well, we finally made the purchase of a hot tub today. We checked out dozens and the one we decided on was the Hot Springs Envoy (HSE). We chose that over the Thermospa Gold (TG). After we talked the Thermospa salesman down about $4000 and the tubs were roughly the same price we made a decision. The HSE ended up actually being about $2500 less expensive in the long run.
We were able to wet test the HSE, but not the TG. It is always interesting walking into a store in your bathing suit, jumping in the tub and watching everyone's reaction. Many people don't realize the reason the tubs have water while on display is specifically for customer sampling.
Thermospa has a lot of complatins through the Better Business Bureau.
