I cook with a Snowpeak stove and .9 liter pot [mostly just to heat water]. For some years, I have used a windscreen I make from aluminum foil. I use HEAVY DUTY foil and fold it double, with 1/4 inch fold-overs on the three non-folded edges. It is about 8" by 26" weighs 1.5 oz.
This screen works perfectly, is cheap, easy to make, and lasts me for several seasons [usually 20 - 30 days each]. I ALWAYS use it when I use the stove. I have none of the problems discussed in the article. It is plenty stiff enough for any winds I have tried to cook in, if sheltered by rocks. I fold it into quarters for packing together with other flat items. As described in an earlier discussion, I keep an eye on the fuel-can temperature if I need to close the windscreen on windy days, but it is never a problem.
I can understand needing something different in some very harsh conditions or if the half-ounce of extra weight is a concern. However, for my purposes, I would not want to fool with rolled screens, stakes, or any other complications.
Of course, I would NEVER recommend this solution to anyone else. It is almost certain that someone would wrap the foil tightly around their stove, blow up the fuel can, and sue me. :-)
