The first link, they don't sell online. They are a multiple location local dealer. The control valve is a Clack that is highly modified so you can take it off a tank adapter to take it in for service and swap it or have them fix it. I suggest that they are very pricey.
The second is a competitor of mine. Every few weeks I hear from a customer of theirs and they need programming information. In comparing their softeners to mine, they usually aren't the same thing, smaller tank etc. and they don't include everything I do. So be careful, you get less from them and next to no help in in sizing or programming. Their instructions are very weak also.
