Hi all, I just discovered this great forum and just in time. I've been researching swim spas. Had for years been drooling over the Endless Pool, not realizing there were better options out there. I have tried out an EP at the factory and really liked the feel of the propeller-driven water, but I don't like the idea of the vinyl liner and their silver/copper water purification system is pricey. I would prefer an ozonator. I looked at SwimEx since someone on another forum said it was "the best". Disadvantage to me is the price, plus ideally I would have a swim area and spa in one unit, but with separate heating. I looked at Master Spa, but after reading all the negative comments about it, no way, plus their sales rep. still has not answered my 2 emails after 3 days. Does not give me a lot of confidence in their customer service. This pool will be located in an as yet not constructed sunroom/greenhouse in hot, sunny Tucson. Does anybody know of good local swim spa dealers here? I'm sure if I go with some place like SwimEx, I will be paying a lot in shipping. I emailed them just yesterday, so still waiting to here more. I want something that will last and not give me a lot of maintenance. I don't expect to move from this residence, so I plan for the long term. Also, outside of the initial investment, I'd like a pool that has minimal continual costs compared to other brands--so looking for good insulation, lower cost of upkeep in chemicals, and since I'm a newbie, I'm not sure what else I should be considering. I'll go solar for heating if I can afford it. Can anybody tell me what the monthly costs are to run an ozonator? I do like the propeller or paddlewheel concepts versus jets, although I admit I have never tried one with jets, just going on what others say. Sorry for so many questions. I hope I've given enough information about my "ideals" that some of you can chime in with appropriate advice.
