I bought some at REI within the last 5 years or so as I have a small burner that I toured with in Spain 15 years ago. However, it's not now listed on their web site. Campmor doesn't list it either. I did some poking around and I think you might be right. The official Campinggaz site lists a bunch of countries but not the U.S. That sort of sucks as I have two remaining canisters that are running low. I like to take the burner when I car camping or do a supported tour where I just want to boil water for coffee. I did the latter just last summer during the Bon Ton Roulet.
