Steve, here is a link to the Vadai Barrels through a middleman. For some reason, I can't go directly to their site, (which was www.vadaiwinebarrels.com), but you can see the products here.
It looks to me like you may save a little money in shipping using Morewine (they may get a better shipping rate than Vadai). The barrel will be shipped directly from the Vadai warehouse in Oregon.
