Gypsy,
I have settled on the BCB commando saw. They are available online many places, the cheapest I found one was like $8 at fatigues surplus. I took a close look at the coghlans model, and it looks like they do not fasten the loops on the end as securely as the BCB. Plus when you take the handles off, the saw can be coiled very small, about two inches in diameter. Perfect for a altoids kit. Good luck.
