I use a Benzomatic blow torch from Home Depot using MAPP gas. It blows very hot. People have said that, theoretically, MAPP could impart a taste to food, but I have never noticed anything close to an off taste, and I love the searing hot flame.
I actually do have a Searzall but realized I’d need to get a new blow torch to fit it, so have never bothered. I haven’t had much of a problem of diffusing the flame.
