I recently came across this burner:
Very reasonably priced and looks very similar to a KAB4:
- 17" cooking surface
- 9" 3/4 heigh
- 210k BTUs
- 30 psi regulator
The Backyard pro has a 8" cast iron burner, while the KAB is 10".. But both are same btu rating.
The major improvement I see to the Backyard pro is that the pot actually sits much closer to the flame, unlike the KAB that needs a wind shield.. Seems like a better design to me.
I haven't found any review of backyard pro online though.. Anybody own or heard of it?
