I finally built my system last spring. I was tired of using propane and was using a 240v 5500w Kettle Rims with a buddy and loved 4 hour brew days. I built a bit simpler of a controller and haven't looked back. I brew in my basement, takes all of 4 hours with clean up, sometimes 3.5 hours. It was a bit more of an upfront cost but, I'm not worrying about having enough propane and it's much more efficient. I have my washer/dryer close by so I tapped into my washer's cold water supply for my chiller. No more freezing my schnuts off with propane or having the hose freeze when you're ready to chill.
