Welcome to our forum.
I think your right on the setup of the Jacuzzi compared to the Optima.They are close, and I have checked them out.Unfortunately the dealer for Jacuzzi in my area is not a very reputable person.I have a couple of neighbors that have bought from him, and his service is "something to be desired" As well as he wasn't all that friendly about letting me wet test it, as all the tubs are cold water, and wasn't too keen on heating them up... :-?As I realize that the Sundance is a bit more expensive, but I think the tub is reputable as well as my connection with the dealer...
