The 3N30 does not seem to be imported to the USA for retail; sales based on a quick Google search. Your linked to source in Germany notes a 30 Euro charge for shipment to the USA. The best buy here is probably the Sanyo QR dynamo hub which is $40 from Peter White Cycles with quick release or $37 without the QR skewer.
