I'm looking for opinions on what would be the best stove to purchase for a Scout troop just getting into backpacking. I'm probably looking for a propane / butane fueled stove since Scouts are not suppose to handle liquid fuel without adult supervision and because of the general safety concerns associated with liquid fuels. Also the stove should be able to handle both boiling water and some cooking for a patrol of about 5 boys during a weekend trip. Please consider durability and cost. Any constructive feedback will be greatly appreciated.
