Wickwerks anyone?

Here's a thing- I'm really after some Wickwerks chainrings for my CX bike as my front shifting is awful- mostly because it's SRAM ...

But some big ramps on my rings would massively help. Doe's anyone know if there's a dealer in the UK? All i can find is US sites- and i'm a bit twitchy about import duty which i'm guessing i'll have to pay ?

Fanks!
