We have a 1bbl blichmann system. Top tier and tower of power. 5, 42 gallon conicals.
We have a great time. And it certainly pays for itself. But only because of some "strange" things. Our brewery is an outbuilding on our residential property. We are outside city limits, and the zoning was already in place. Plus, the LHBS and I combine orders for some savings there. Getting licensed was actually fairly easy. It's the monthly reports to the state, and quarterly to the feds that's a PITA.
It's a hobby, not a business. We're still homebrewers really, just licensed to sell the stuff. When I look at the "pimp my system" board, many folks have fancier stuff than we do.
