stoves

Hey all... I am in the market for a hiking stove. Weight is critical selection criteria, but so is dependency. I'm not very technical minded and easily peeved when something doesn't work like it's meant to. Just need something for hikes up to a week. To boil water, cook simple stuff. I've been told gas is best? is that true? and if so - what brand. I am just starting out on my hiking life - I don't want to spend heaps of money just in case i get bored with it in a few months. But happy to spend a bit for quality...
