I have used global priority with them once to ship dvds (including the cases) to the Netherlands. It was pretty fast (3 days, I think), and no duties, but your mileage may vary, of course. I think the risc to get caught by customs is even smaller for disc+artwork shipments only.
But it's too bad that we have less choices. I have used the FedEx option also, and I loved the speed and tracking possibility.
