well i have looked at what the postage would be to the USA from here for the item, and it is approx £10-£13. this does need to be confirmed, but I have used the weight cost on the royal mail site for insured signed for.
So an option would be for someone here to buy it and post it to you, or you could ask the company to mail it directly.
Look into it and see if the cost is acceptable compared to New Bonn prices.
