Actually those butane stoves are a great prep item.....Why?

- they're cheap to buy and operate....I found them for $19.00 and the butane canisters 4 for $5...cheaper than propane cylinders...

- they are easy to operate for non hiker/prepper people.....I have many expensive hiking/camping stoves but they are harder to operate and assemble....these stover are similar to a kitchen range or hot plate that most will recognize....

-fuel continuity.....they also sell a lantern that uses these butane cylinders....easy stocking of fuel....

Even in non emergency times, I find them handy during backyard cooking.....
