Hi Lee - I bought a couple of the Italian surplus blankets several years ago to keep in the cars. They're great - thick, heavy wool. The ones I got came reeking of mothballs, but they aired out (the customer notes below the blanket has people with various suggestions on how to get rid of the smell).
They had them on sale four for $60 for a while, and while I tried to convince myself I NEEDED that many, they seem to have realized what a steal that deal was and they've raised the price. I really wish I'd gotten in on that.
Don't know about the other blankets, although the Swiss one looks pretty good, too.
