I have used a propane torch (the kind to heat asphalt) to start a pile of charcoal. That works prety good.
Actually, I use a torch too (I just didn't bring it up). I use MAPP gas. Even though it's a little more expensive than propane, it burns really hot and I find that a can lasts me a year or more & I BBQ or grill at a bare minimum of 3 times a week.
With the grill I use at home, I can get temps up to the 600-700 degree range in about 15 minutes after starting my charcoal with the torch. If I'm doing a low and slow cook I start it with just one small section of the charcoal pile going.
