KAB6! It's an awesome banjo style burner in a no frills 20 in. stand. Once the air flow is set properly, I get a gorgeous array of blue flames that efficiently heats whatever I put on top of it. Best $89 I have spent on brewing.
+1 Blichmann Top Tier burner. Best purchase I've made. So quiet and soooo fast compared to my bayou classic. So efficient....The money you save on propane will pay for itself in a year or so depending on how much you brew. Wish I wouldn't have wasted the money on the bayou. Now don't know what to do with it.
^^^^This! Probably my best investment when I started 5 years ago. It's continued to serve me well as I've expanded my system.
Quiet, efficient, reliable.
