$600?  US Dollars? 

Shipping by UPS does cost more than postal service, but it is much 
faster and has the advantage of actually getting there at 99.9+% rates.  
Our experience with postal service was that items would be lost between 
2 and 3% of the time depending on the country.

As for customs fees, those should be the same no matter what shipping 
method, right?

J1001 is all grounds, no power.  Rev 3 was designed without a fan, so 
you'll need to solder directly to the pins of the power connector.
