Has anybody had experience with both Blichman burners AND cheaper burners such as Bayou Classics? I noticed the burner on my SP10 is looking really rusty so I am thinking about a replacement. I just don't know if it is worth 3 times the price to go with the Blichman. But if I thought it actually performed better, would save some fuel, and I wouldn't have to replace it in 2 years, it might be worth it.
