Hi Guys,
I have been fortunate to travel all over the world and here's my opinion;
I've sent via Fed-x... IN A HARD SHELL CASE ALWAYS
it works and you can insure it. But the apes at the shipping co. are not easy on it so you may want to remove and hand carry the hard drive. But it does work.
I have also gone the airline route...
DOOR check it so you can WATCH them put it into the belly of the plane
I have also purchased a seat for it and in a soft bag straped it into the seat next to me. Can you say $$$? It will not be allowed in the overhead.
If you travel often (like I use to you) you can become a 'TSA Certified Shipper' which at the time included a interview and a finger prints but at the airport things were much easier and they don't ask you to 'please turn the unit on and operate it'.
On ballance... if its a one time deal the Fed-x sounds like the way to go.
Its enough to make ya want to take up guitar!
Good Luck
Tom
