I am making the move to BIAB from extract brewing and am looking for the best 10 gallon brew pot and burner to purchase. I'd like a pot with a thermometer and spigot that has gallon marks etched into it. I've seen a lot out there, but don't know which one will heat evenly and hold up the best. Also, what is the best propane burner out there.? How many BTU's should I really need for a 5 gallon batch? I've also read where some say that a 10 psi regulator is enough and others who say nothing under 20 psi is acceptable. Help me sift through everything!
