Its been about a year since I was last shopping around, but I really wasn't too impressed with the tub scene here in Dayton. Seems to me most everyone buys from Watson's because it convenient.
Of course, I never ended up purchasing one (bought a house that had a leaky late 80's Jacuzzi), so I can't comment on anything other than my shopping experience.
There is another spa/fireplace/patio store down the road from the Sundance dealer a mile or two, Morgans, they may be worth checking out as well. I can't remember what brand it was they sold, but sales guy was friendly and no pressure.
Edit: Remembered the store's name.
