FWIW, Walmart.com has the Intex SWG for $139. I am going to give it a try. Carl is right, a few minutes a day with bleach but in my case, going to the store to buy the bleach, not to mention how many tshirts of mine have bleach spots on them (yeh I know, wear an old shirt) gets old fast. I dont know what to expect but if I can get 2 seasons from the unit I'll be happy.
