The Super-Fi order page is up on Ultimate Ears. Just ordered my 5pros. Their site says that all orders will begin shipping on June 15 via 2 day air. Total price including shipping and taxes (live in CA) came to $290.00 or so. Can't wait.
The reason it was so expensive to ship to UK is b/c they are doing it via Fed Ex 2nd Day Air. If you order over the phone then UE may be able to provide other shipping options for international delivery. Import Duties may play a factor in the $65 as well.
