Pruned Hands,
We bought this one for a couple of reasons. The “moto- massage DX” jets are really nice. I’ve had back surgery and they seem to “hit the right spot” for me. We liked the depth of the Grandee also, 1 to 2 inches doesn’t seem like a lot but it does make a difference. I guess the real thing is that this is like any other major appliance, your going to have it for a very long time so we spent the extra money and got what we really wanted. The cycle between the 6 LED lights are cool at night too.
I was considering a Sundance also but I would have had to buy from out of town. So the deciding factor between the two brands was having a service department in town if needed.
