Yup. Same spa.
They are supposed to go out the door for less than $5000 for the big one, all the way down to $3000 for the smallest/simplest. I have talked to many dealers who try to price them as they would their other lines -be it HotSpring or Caldera - and they don't have the features to support those prices.
They are fine, basic tubs: the big one has two jet pumps, full insulation, an acrylic/fiberglass shell, wood our plastic exterior, two colors, Gecko controls, no diverters, and the bottoms are sealed with a heavy sheet of plastic protected by pt lumber.
I would say these would be a good option to consider over a big-box tub - and you'll have the backing of a HotSpring dealer.
These pics are not to scale - the biggest tub is 7x7 and the smallest one is 5'10" x 6'8"
