i had a lot of options and went to every dealer in the area. sundance, hot springs, marquis, jacuzzi, caldera, bullfrog. All the major brands. even master spas. I liked the design of the sundance w/ the predictable open layout (i have kids who jump/splash around) and center foot jetting. I also liked the UV + ozone combination but it was less of a factor - and honestly now they both feel like a liability.
I was actually leaning towards bullfrog when i visited great bay, and would have gone in that direction but ended up getting a better deal on a sundance.
what swung me to that dealer in particular was the professionalism and service. to me it felt like i would get the best service after the sale of all the sundance dealers in the area.
