The dish on EBay.uk is about $105.00 U.S. shipped and is the cheapest price including shipping that I can find right now.
I regularly buy products from vendors in other countries and I never have to worry with US/UK customs and export/import forms. These purchases are less than $750.00 U.S. per transaction, and are for personal use. The vendor or seller fills out the forms needed for shipping into the U.S. Larger transactions or items being shipped for resale will usually have some extra charges.

Private party is different, and I have to do the customs form which usually takes a minute or two when shipping something to Canada or other countries.
