I hear ya, Tim. I dropped $1600 back in 1992 for mine. It was specifically designed for carpet cleaning TM's by a company out of Southern Ohio. The local Kinetico dealer had a shit when he found out that I bought it mail order......they have protected areas. The system was designed to bolt right up to your TM, and included a water tap to fill your sprayers with soft water. The uniqueness of the Kinetico is the trouble free onboard recharging that require NO electrical power to recharge (they recharge according to water usage), and while one tank is recharging, the other is supplying non-stop soft water to your TM. The brine is discharged into your waste tank (or a separate holding tank that you drain later).
I ran across some in the local paper last year, but was too late to buy them. I'm going to call the local yokel tomorrow and see if he might have some used or repo units for sale. These Kinetico dealers are like shady used car dealers.....they want to turn you upside down and shake out your pockets. All there sales are commission driven. They would be the SS'ers of softener dealers.
