Not to hijack this thread, but I wanted to point out a relatively new eBay program for the sellers that have commented on this thread.
If you are eligible, you can opt in to eBay's Global Shipping Program. I have been using it for the past month or so and so far have been really happy with it. From my end, the buyer pays me whatever I have specified for my domestic shipping costs. The buyer then also pays eBay the international shipping costs and customs fees. So far this has been just slightly more expensive for the buyer than had I shipped the item overseas myself (but they don't know that as they don't see what my price would be). Then I ship the item to a US international shipping location and they handle everything from there. They send the item overseas and they are responsible if anything is lost or stolen. And the tracking has been much better than when I was sending things myself through USPS. The program is only available for certain countries (maybe 20 or so?) but I know they're planning to expand to more. I have it to where I now offer than program to the countries eligible and that is now all the international shipping I offer.
Just wanted to give you all a heads-up in case you weren't aware. And I know my first thought is that a 'helpful' eBay program for sellers usually isn't helpful but so far this seems to be a pretty nice thing. It really takes all of the bad things of international shipping off of the seller's shoulders.
