I've read quite a few threads regarding problems of every sort when buying what appears to be a good deal on burners. What are some important things to keep in mind? My pot is 14.5" in diameter. It's an 8 gal aluminum pot. For now I don't have any plans to upgrade. I only want to do full boils of 5 gallons. The LP store sells a very basic burner with no legs that looks to hold almost any size for $25. Should I be considering regulators and PSI?
