Have you tried the delightful eBay seller, Janette's Rare Yarns? Nice, nice lady who sells Rowan, Jaeger, Noro and other premium brand yarns at very good prices. Also needles, beads and other goodies. I'm in the U.S. but I've been a customer for ages, and don't mind paying the extra postage (which is quite reasonable).
Here's a link to her eBay "store."
