My Jacuzzi dealer said that Sundance is a more expensive but lower quality spa than the Jacuzzi. Â No surprise that they would say that.
I looked at the Sundance spas at Pool City and was not real impressed with them. Â And I was very concerned about the part time kids selling and installing the spas. Â Between pools, Christmas trees, and patio furniture the spas seemed like an after thought to make a few quick bucks off some vacant floor space.
The local Jacuzzi dealer is far more professional and concentratres solely on hot tubs. Â That means that when my tub needs service in December, I won't have to wait for the repairman to finish decorating a tree.
What I have learned in order of importance to me:

#1 - do a wet test because the tub must fit you.
#2 - pick a good dealer because when things go wrong, no one on this forum will come out and fix your tub.
#3 - the price. Â Don't save a dollar now so you can spend 5 later.
We liked the look and feel of the Jacuzzi and I have had good reports from other buyers about the dealer so I bought a J-385 even though it was about $1000 more than I had budgeted. Â I expect to be happy with it and the dealer for a long time.
stl-rex - I just bought a J-385 for $7589.99 plus tax with a few extras tossed in. (
