The gas type flame guns are very effective, but only really useful on hard surfaces or where there are no desirable plants. I use ours on weeds which seed around as the heat kills off the seeds even if the plant survives.
You really need to go over them twice too. Day one dries out the tops and then Day 2 burns o f the dried remains. They do kill off Dandelions though.
Never managed to set fire to anything except the incinerator with mine.
