I have been using a small propane torch that my father in law gave me to light my egg. Seen all the talk about mapp gas. Decided to buy a new swirl nossle mapp/lp plumbers torch. Its about double the heat output of my old propane torch with a standard end. So I decided to check how much hotter the mapp gas was vs lp. Took a piece of steel and used my timer and IR thermometer. Timed it for 30 seconds. The new torch under mapp heated it to 365 in 30 secs. The same swirl torch with a lp bottle heated the other test steel to 345 with the same time, distance, etc. I really cant notice much of a difference between the two. Definitely not worth the 12X the price for fuel. The new TS8000 burnzomatic puts out a ton more heat than my old Surefire T111. The same time on the T111 is 275 deg.
I also been reading about all you guys using the Harbor Freight Torch so I just picked one of these up. This is by far the best thing I have used to start my Egg. I have almost every method you can think of to light the BBQ. Even a gas assisted chimney. The Harbor Freight Blow Torch was the best 16 bucks I have every spent. If you have an egg, its a must have. You light the end and adjust your flame. Heat is even and very very fast. Wish I would have bought one of these last year.
