OK, so I did forget one thing -- I looked back through my email threads and there's an ISF customs form you need if the value is over some threshold. That requires as quick a turnaround as you can perform, I guess. I saved all my communiques, so if you'd like more detail, I can forward you some good info from my discussions with Amagasaki and All Ways.
Flavien is a great guy to work with: tons of relevant experience, helpful, near-insomniac (his replies were timely almost around-the-clock), and a complete, utter, delinquent gearhead. I could not recommend someone with more confidence.
