I got 2 Xenarc screens through from the US to the UK, cost: $868 (about £550)
A week after they were delivered I had a customs form on my doorstep wanting £100 customs fee
Maybe if it's marked as Gift on customs form it will be OK. I've had 3 things sent through from US as gift, no customs. 2 things as merchandise, got hit with customs fee.
However much it is, they will charge you the 17.5% VAT
