When hiking in Norway, we cook exclusively on burners. And today I went to a gas station in Oslo to buy gasoline for my MSR whisperlite. Quite expectedly, they refused to pour fuel into pet bottles and I had to buy this nice canister for gasoline. But even taking into account this purchase (75 CZK for gasoline + 125 CZK for a canister), gasoline was still cheaper than the same amount of gas in cylinders.
