I own alcohol, iso-butane (cartridge),liquid gas, and propane stoves. Each has its niche. For prolonged domestic problems, I plan on a propane stove (big, heavy, green bottle).

You can shop around and get either a two burner or one burner model for around fifty bucks. The two burner will be more versatile- you can brew coffee and fry eggs at the same time. I have basically phased out use of my classic liquid gas Coleman stoves in favor of propane - it is simply much more convenient and dependable. The latest models are compact and relatively lightweight - for a camp stove.

Alcohol and iso-butane are great in applications where weight is critical, but for domestic situations, it is propane all the way.

Use outdoors if at all possible. CO is a real problem with any stove. CO detectors are available and can be installed before hand.
