Does the SP01 really offer so much more than its earlier ancestor
The short answer is NO it does not. The CZ-75 SP-01 is a polymer frame pistol with the new trigger system. From what you are saying about price, it seems that it is a supply and demand issue not a "is one better than the other" issure.
I am not sure you will be able to find a Pre-B new in box CZ-75 here in the states, so a purchase of one of those would be to your advantage.
Your question poses more problems than answers.
I've been posted abroad for more than 10 years and where I am in Asia
Asia is a large area and I am not sure a Foreign National would be allowed to carry a firearm in the country you are at.
No idea of what caliber the CZ-75 you are planning to purchase is, 9mm Luger (9x19) or 9mm Markoff (9x18) or someother caliber. What would be your supply of ammo?
If you are planning to return to the US how will or if you will be able to transport the weapon home, import permits or just sell it overseas and which one would bring you the most return on your investment if sold there. (CZ75 or SP-01 resale price)

If you are military or embassy staff and are allowed to carry a sidearm, wouldn't it have to be an M-9 or are you allowed to carry personal firearms.
As you can see, your post brings up more questions than answers as to if you should spend the extra money for the SP-01.
If you were here in the US I would say get the SP-01 and get your best price from Bud's, but they will not ship overseas.

My persoal choice was the CZ 75 P-01, shorter and lighter.
