Hi there.
Up here in the frozen wastelands of Canada, it looks like Mountain Equipment Co-op sells them, but it also looks like due to some kind of wierd 'un-free trade agreement,' they won't ship them out of Canada. If you're making any trips to Canada or know people up here tha could mail them to you, it's at least one option. The exchange rate against the Cdn. dollar is good right now too. Here's the MEC link to evolution picks:
