I chose the cheapest option with B&H customs clearance / brokerage, base cost is roughly $10 + taxes. I've done some rather large shipments and it was only $25. I highly recommend it.
Paul, I've had those brokerage issues with UPS several times, even when shipping their world-wide super-duper-no-brokerage-we-promise methods. I've basically stopped online shopping from the states unless they ship it USPS - However, with B&H, I've never had a brokerage charge. B&H's system is excellent.
