Thanks
The trouble with TW is that you have to pre register with them and fax (how delightfully retro) stuff to them before they'll accept an international order. Lousy way of doing business, so I won't!
Dry Creek looks very promising, but you can only order directly if your in the States. I might try emailing them to see if they can do a shipment, but I suspect that it will be a bad deal if they're not used to doing it. The shipping quotes are usually ridiculous. If I could find a supplier on ebay it would be too easy, but I can't. Jeez, it's hard to spend your hard earned sometimes!
