Which stove?
My very limited experience with alcohol stoves(Trangia)was basically positive as long as all you want to do is heat water for coffee and instant whatevers. It is a fuel hog. I estimate that one btl of Heet will last about 1/3 as long as a propane fuel cannister for my Pocket Rocket, making Heet more expensive. The combo of stove plus Heet is about 1/2 the weight of the Rocket and cannister.
I'm considering adding the Trangia to my kitchen as a second stove and use it to heat the water for my coffee while cooking my usual toast and oatmeal with the Pocket Rocket.
As fuel cannisters can be hard to find on long tours, the alc stove is a decent backup.
