Burner to support keggle? Bayou KAB4? Blich? Other?

[eko]

What burners will support a keggle? Is the Bayou KAB4 big enough, or do I need KAB6? I've also looked at the Blichmann, but considering I can get a KAB4 for almost half the cost. Are there other burners I should look at?

Blichmann is. I have the floor burner and the included arms go out to fit something like a 20" diameter pot. I even have the taller legs so it can be drained right into the fermentor.
