Polaris 380 all day. Everyone who has one says a Polaris (any type) says that they can't imagine maintaining their pools without one. I just recommend the 380 because I think it's superior to the other types. They are a little pricey, but they are worth it in my opinion.

I'd recommend Sundance first and second, but I work at a pool and spa store that exclusively sells Sundance so obviously I'm going to be a little biased. However, we deal with a bunch of different tubs (repair wise and so-forth), and I recommend Sundance over any other tub for a lot of reasons but ultimately because of their patented jet technology. I've worked on, and been in many tubs and I personally think the hydrotherapy is unmatched. Consider wet testing a Sundance spa and see how you like it. If you don't like it then I'd recommend HotSprings over the others that you listed. Good luck choosing a spa! I know it's pretty exciting.

Clear Ray is a water purification system. It is basically a natural ultraviolet light used to sanitize water. Within seconds of the water entering the tub, it is sanitized. And yes, that quote sounds like a good price. Enjoy the tub!
