Welcome to our forum.
Well we went and tested some spas last night, and we LOVED the Tiger River Caspian!!! I'm thinking we'll wind up buying that one. The foot dome is wonderful!!! It only is available in 220, so that took care of that question. They're willing to sell us the Caspian with UV ozone, a cover with EZ lift, steps, chemicals, in home orientation, and delivery and setup for right around $7300.00
