I recently purchased a Weller WPA2 Pyropen Professional Self-Igniting Cordless Butane Soldering Iron from Amazon for $142:

Bottom line: It is perfect. It heats quickly and cools quickly. (Kind of like how chefs like to cook on a gas burner rather than on an electric burner because it takes an electric burner longer to get up to heat and longer to lose heat while gas heat goes on, up, down, or off quicker and is more easy to adjust.) It is now my go to iron.
There is a vent on the tip holder (not pictured) to vent the gas fumes (clean burning clear butane). I used that vent to shrink heatshrink tubing. Not as quickly as a Milwaukee 1200w Heat Gun, but good enough for one stop shopping outdoor work! Apparently there is also an optional heat shrink air tip, which replaces the soldering tip, which I have no doubt would shrink tube quickly.
But I will likely use this gun indoors for everything but circuit board work. It is that good. And when you put it down on the bench, it doesn't pivot and burn other stuff on your bench like a corded iron or gun does when the cord is pulled by gravity. And you can even put its sheath on after you have turned off the flame, the sheath is vented and designed so as not to touch the tip.
Some Amazon reviews said it works badly with bad butane. I bought this Master Appliance 11799 Ultratane Butane, 3-3/4-Ounce, 106-Grams - Pack of 4 butane which was recommended and it works great. Period.
