I am in the middle of the same thing!!! I shipped a cue to Taiwan, and it is confirmed to have reached customs, but beyond that is anybody's guess. I definately had insurance and I shipped it priorty mail ( supposed to be 3-5 bus days). I am in the middle of going through the claim procedure now. Let me know how this ends for you, and give me any tips or problems you encounter along the way. I will do the same.
BTW I did get my postage refunded no problem, just waiting for them to process the insurance claim.
