Ebay usually at a decent markup, even used. They've been out of stock for two years. I sold mine well used (never fit that well) for about $50 more than I'd paid for it, and that was last year. If its any solace though, it's honestly over-hyped. It's too cropped to be useful in cold or wet weather, and the tin cloth makes it uncomfortable in warmer weather.
