I got this Bayou Classic
and a 40qt aluminum stock pot so I can brew outside. Now I don't have to listen to the family complain about stinking up the house. I cannot believe how quickly this burner heats up water. I think it's cut an hour off my brew day just in heating water/wort. Got both items, from different locations, for $100. I got the stock pot from a restaurant supply store and is designed for high volume use (3/16" thick).
Should have bought these things months ago. The amount of hot break I had with the burner vs. the stove is amazing. Almost boiled over with only 3 gallons in the pot.
