Hi,
im a complete newbie from the uk and faced the same problem when wanting to buy a falcon picap .
I have ordered through a company called shipto, sign up for free they give you a US address[P.O Box] you go onto the pixel controller website order your item and in the checkout process where it asks for your address put your new US address supplied from shipto and your item is then shipped to shipto who then ship it onto you in the uk.
There is a huge selection of delivery options to choose from and a customs form to fill[yes we have to pay import fees} you only pay a handling fee to shipto which is about $2 dollars .
