Call me crazy., but I was doing cartwheels when I first got my hands on a Raven 440 rate control setup. When you set that thing on 20 gallons it puts on 20 gallons. Those old twist valves to regulate pressure never worked long for us. I was the same way by a light bar. Where it's not cool at all is when that stuff fails to work. I agree with Jed some of those planter setups are going to be a nightmare when connections and wires and hoses start going bad.
