Wow! Never felt better about a purchase. Best thing I've done in years for my health, both physical and mental. Bought a 8x13' swim spa from Southwest Pools and Spas. As an "Older" high school and college baseball umpire, it really keeps me loose and in shape. The "social" benefit is also great. Sit on the edge read or listen to the four speaker stereo, or just visit with the "significant other" before doing "lapes" against a variety of currents and exercises. It fast becomes an almost daily habit. Heating it to a desired temp in the winter (about 90 for me) is not problem. Doesn't use a lot of electricity, but the benefits outweigh the minimal cost of operation. Great, no make that outstanding, service from Melinda at Southwest Pools and Spas. And oh, BTW, get a prescription from you Doc, and it's tax deductible. Check it out at the Gilbert location across from Sprouts...pete
