AFAIK there is no import duty on still camera equipment coming in to the US. I bought a dSLR from Ffordes in Scotland last week, they subtracted the VAT from the price and I paid no tax. mwooten is correct, your CC company is delighted to ding you with a finance charge for the foreign transaction. It is worth buying from the UK at the moment as the $ is way up against the £. With the great exchange rate and a dealer sale I got the dSLR for 29% of the price at B&H in NYC on the same day (I just worked that out 😀).
