I'm a "Culligan Man" who just purchased a home that has a Sears water softener in it. I just want to mention that they are designed with built-in obsolescense. Anytime the resin supply is within the brine tank and the electronic components are in the corrosive salt environment, the softener will last approximately 4-6 years. Of course, I'm biased towards Culligan, but we do have the best products on the market, best warrenties and best service. It's a cost versus price issue. The price may be more up-front, but the cost of maintaining the unit will be virtually zero since the average time period of a service call on a Culligan softener is 14 years from date-of-purchase. I'll be getting a Culligan when my inherited Sears quits. Have a great day!
