I always carried isobutane in the winter. The plastic tube in the bottles can get very stiff in the cold, sometimes the opening in the end is above the fuel line if the bottle is lying flat and you will not get enough pressure. it is important to keep the fuel bottle vertical with the bottom stuck in the snow. But cheap is not a modern BP term. Oh yes I have a liquid feed stove.
