In my area, they dont even have a store front. I dont know about the service record on them but I would find it to be difficult to track them down.
I will say that a friend from work has one a swears by it. I have read many posts which do not recommend them.
It is all personal preference. If it were my money, I would be sticking to the reliable brands, Sundance, Arctic, Hotsprings, Artisian, D1, Beachcomber, Coleman, Jacuzzi. These are the tubs to be looking at.
