The cost for me would be the worry that it is going to be smashed to pieces in transit and what would you do - ship it back again...
I have been to international shipping depots and seen the automated sorting systems, where things go round the ceiling of a warehouse then get dropped down chutes - inevitably some fragile item, is siitting at the bottom of the chute, when a huge refrigerator or similar, comes sliding down at speed, completely flattening what it lands on!
I would never risk anything as fragile as a DB to this...
I remember there was a thread round here where a TBer was shipping a DB from the US to Scandinavia and it was damaged in transit...can't remember the outcome, but no doubt painful.
