No idea. We order a custom system so you can't really go by their pricing or model call out. We had used a 4 pump automatic with the control on a tether, but too many people thought the controller was cheesy. We have since switched to a one pump (to cut some weight) and mounted the control in the step well. Very easy to activate when standing out pride the doorway.
