Personally, if I were starting over, I would go electric. Propane gets expensive and always runs out on you at the absolute worst times. That being said, I have both an inexpensive turkey fryer propane burner and a couple more expensive ones (bayou classic and hurricane) and they all do the job. My hurricane does a better job on 10+ gallons but I make far more 5 gallon batches and on those I'm constantly turning that one down because it's such a monster.
