I wet tested a Sundance Optima and a D1 Chairman II and Californian today.
The Optima and Californian had more bells and whistles ...
LCD lights, waterfall or fountain, however I felt most comfortable in the Chairman II (unfortunately it cost more than the other two). Also their Alpine color Ultra Life Spa Shell has a lifetime warranty.
I also may wet test the Marquis Epic.
Any comments re Chairman II reliability, ease of use and shell would be greatly appreciated.
I was quoted a price of $9,000 including stairs, cover, cover lifter and delivery.
Thanks very much for you input.
