Haven't looked at the gasoline powered one yet, but the mil thickness required for moving up from propane is not worth it to me. Lots of experience with LPG, I could supersize it easy, doesn't scare me a bit. Gasoline, worries me to this day, because of experience. LPG blew my unibrow off and apart, grew back with a proper gap, but brows now run down the sides of my eyes. Even with that, I'll leave gasoline bombs to him.
