Outdoor burners

I've been looking at a few different burners for doing 5 gallon all-grain batches, and I've seen some reviews that suggest the Bayou Classic KAB4 is some what difficult to control in terms of getting the amount of heat to produce a nice rolling boil without boilover. Does anyone have any experience using this burner? Is there an easy solution that you've found?

Also, I would be curious about your thoughts on the KAB4 (210k BTU) vs. the SP-10 (185k BTU). Does the difference in BTU really matter when only doing 5 gallon batches?

Thanks!

My original 5 gallon batches was done with a 60k BTU burner that worked with no problems. As long as you can control the output of the propane tank, any burner should be fine. With what you listed above, all will have no issues with 5-10 gallon boils.

This is the one I bought and it works great! Got it cheap through Amazon, although it does sound like a friggin jet engine. The rating on it is good and puts out about 185,000 BTUs.

I got a 120k BTU burner from Academy (their house brand - "Outdoor Gourmet") for $30. Its quiet, efficient, sturdy, and cheap. Not pretty though.

Also, whatever burner you get, I highly recommend getting a one that has only three legs, not four. With four legs the surface you sit it on needs to be perfectly level else it will rock back and forth. There's no way for a three-legged burner to rock like that.
