There's a nice Surly on the CTC forum for sale right now. Think its for someone around 5' 10'. Now if someone not unknown on these boards gets his Thorn US franchise Surly will be in for some stiff competition 
Here in Oz I can get a Surly for about half of what a Thorn would cost me without taking into account the freight component.
If you are importing into the US in volume you might get closer but IMO Thorn would be competing with Co-motion and not Surly.
( Not that there is anything wrong with Surly, I ride one!)
