Have a used in great shape SS Brewtech 20 gallon brew system.  1 mash tun, 1 hot liquor tank and a boil kettle.  Comes with a Blichman hellfire burner and the rolling cart.  The burner is set up for natural gas, but have the parts to go back to propane. What you see in the pictures is what you will get.

This system has been very well maintained and has a lot more brews left in it.
