It looks like the UE 6000 will be somewhere around £50-60. http://www.amazon.co.uk/Audio-HiFi/b/ref=NONE?ie=UTF8&node=2589474031 - Lightening deals, in 5h50min since this post. edit: disappointing, ended up being £74.

US doesn't have VAT... The only reason Europeans don't use US sites to buy stuff is because after VAT + shipping + fees the cost will be higher than European counterpart.

I think this will incur a ~20-30% VAT when importing from USA, along with other possible fees depending on where you live.
