Man when I built my setup it was blichmann or polarware, I would love a stout or brewers hardware but they need a liquid level like blichmann's. I have punched holes in my blichmann for a herms setup and used cam locks. I can pretty much pump wide open since the cam locks are so restrictive. I have seen (compaired to my cam locks) massive flow rates with a march pump and triclover fitting using the same 1/2 inch plumbing. Now brewers hardware just need a good liquid level, even it it was just scribed in on the inside of the kettle, and a chugger pump with triclover fitting already on it.
