+1 for what TFC Rick said. In my experience, you don't need a windscreen if you use a chicken can with holes drilled in it and a notch cut out for stick feeding. Make it look similar to the BB potstand and it will perform well.
They rust like crazy if you get them wet so be careful of snow and rain.
The potstand made from a chicken can will work with pretty much any standard alcohol stove and you can use the top of the paint can as a priming pan.
