Cool.
I've been running a pretty simple, no-sparge setup for the last 2 years: a 10 gallon Spike kettle, a 10 gallon SS Brewtech insulated mash tun, and a Chugger pump. I can easily perform a hockkurz step mash with it, and I feel it's enough to make great beer.
I have, however, become interested in the purported benefits of continuous circulation and the ability to run any mash profile I feel like, so I just bought a Unibrau v3, which I plan to use solely as a mash tun.
