Hi!
I just made my own alcohole stove. It was made of two coke cans and it works great. It looks something like this (from the page linked below):
You can't find any lighter stove than this. The plans for the stove I made can be found
here. If you get interested in this, you would probably love
Sgt. Rock's page aswell. He has made several different alcohol stoves. These stoves are great for small trips when the weight is important. For all the other trips I use my Primus Himalaya Multifuel stove :-)
