Burner for 55 gallon drum

[thrstyunderwater]

In at attempt to up my manliness level, I've acquired a 55 gallon stainless steel drum to do boils in.

I'm wanting a burner that's up to the job. Recommendations? I'd like to be able to switch it over to run on natural gas.

Bubba's might give you some ideas, but I think you can do better $ wise building your own using a banjo burner.
