For a US dealer, you can't beat Wayne at The Touring Store. He absolutely refuses to sell you something that won't work in your application. His web site needs updating, but his stock is up-to-date. (We talked about the Airy and the Carry back in May, and I bought a newly redesigned 2008 Cosmo before they were up on the Tubus web site.) He's on vacation until next week. Give him a call then.
BTW, the Carry will be pricey because it's made from Ti. If you like that style, it looks just like the "old" Cosmo, which is bound to be cheaper since it's stainless. Wayne had those still in stock as of two weeks ago.
