I use the butane stove for cooking during warmer months... It's not much good during the cold months.<br /><br />To buy some cans, try<br /><br />1) Amazon<br />2) Menards or other home improvement / hardware stores<br />3) Oriental grocery stores<br /><br />The prices sort of fall from low to high in that order. If the weather is warmer (above 40) you can get more heat out of the butane type stove. It does a fantastic job for quickly cooking veggies and searing meat in a stir fry. On the downside, I've burned eggs too easily with butane. :/ <br /><br />Brad aka V.T.
