Figured i'd post a reply after some hands on with the burner I ended up going with. With Northern Brewer offering 20% off (excluding Blichmann), I ended up getting the Edelmetall burner, steam punk aesthetics aside, I've used this to cook up 25 lbs of potatoes for the holidays a single batch of beer. This thing is whisper quiet and feels to be rock solid in construction.
Without using the Blichmann I can't comment on any comparable traits, but the wind screen is more than effective and I think the inclusion of only a 10 psi requlator is perfect. Sure I could get a much larger flame with 30 psi, but this seem to stress the tank less, and realistically we do not need flames licking up the outside of our kettles for a quick and solid boil.
I think within a couple minutes of connecting it to my tank, I was able to dial in a good air/fuel mix to allow only blue flames with enough fuel adjustment left to really bring this burner up to a fast boil.
