Anyone ever install one of these babies? Got any advice for manufacturer?

My goal (maybe can achieved some other way) is to get a constant flow rate to my shower. I have a well and pressure tank, and my pump is set to turn on at ~35psi and off at ~50psi. I have recently installed an on demand water heater, and it does not have thermostatic control. So the water temperature is raised x degrees at x gpm. When the pressure runs down to ~35 (less gpm), the water is hotter, and when the pump kicks in to boost the pressure back up (more gpm), the temperature dips. It's not a terrible difference, but I like a consistent temperature. Possibly I could use a pressure regulator and set it at the lower end of my range?
