Good solid state switch controls

[Rockwind1]

Finally going to put a float switch in my tank which is going to control 2 selinoid valves for filling up the tank and then draining the riser during cold weather I also have two of these old Warwick control boxes That control my lower submersible pump and another jet pump. I wanted to replace them with some solid state switch controls

What are the best or most commonly used solid state switch setups

I think Warwick makes solid state as well. Also look at BW controls.
