I buy a lot of archery kit for the US, both new and used, and you just have to bite the bullet on VAT and Import Duty. When I tell my contacts in the US that we get charged 20% VAT even on used items, they cannot believe it.
First time I got caught was returning a Chris King hub to the US for a FOC warranty repair. When they sent it back I got a hefty VAT bill. I created merry hell with HMRC, and to be fair they were very sympathetic, but said they could not change the regulations, when I asked who could they said " The Chancellor of the Exchequer"...ah, right, well, that's that then
