In Sweden incl taxes 3016 USD
As a pro 2400USD with VAT deduction
Theres in no problem to buy the lens from US but Canon Europe does not like to take care of the lens from US if something is wrong. And there are a 25% VAT of gods from US if the lens are declared into Sweden in a proper way
So don't declare. 
I actually have a friend from Sweden who travels to NYC twice a year. During every visit, he goes to B&H and packs his bag full of gear. He never declares it when he gets back home. Just walks through the customs with a smile on his face.
I've done that a few times, not myself, but buddies of mine travelling. The problem is, IF you get pulled over at customes it's YOUR responsibillity to prove to them that it has been either declared (if bought from elsewhere) or that you bought it in your country, Norway in this case. That means if I travel with a Norwegian-bought lens, used or new, and I get pulled over on my way back and can't provide a receipt from Norway for the item in question, I have to pay the taxes of NEW retail price. This is even if I buy the item used and it's 10 years old and it's still in sale. So I might save quite a bit with sneaking it in, but if I'm unlucky, it would cost through the teeth to keep it.
The other thing is you can't sneak anything in unless someone you know is actually going to BH, buy online and taxes are autmatically added, and yes, they add taxes to the SHIPPING costs as well.. Greedy bastards...
I shoot my 24 veryvery much between 1.4 and 1.8 and I've tried a 24mm f2.8 for the same type of shots, and it lacks that nice soft 3D-feel the f1.4 gives. However I could use both, because out shooting with flash or something I could change the perspective in 0.1 seconds by zooming and have much more options for my images.
It took my a while back in the day to realize that 24-70 isn't about getting closer, it's about changing the perspective. By then it was already sold.
