Check out the Bayou KAB4 or 6 (larger base). Its the same burner in the Blichmann. I have one of each and just bought another Bayou for building my Stand $90-ish on Amazon.
It's 4x the BTUs if I'm reading that correct? That's nice! However it doesn't look as sturdy as mine. Can it hold a 15 or 20 gallon kettle full of wort?
