Drewski, correct, no tax or duty in USA.
That's half the battle over then. In the UK we're really stung for tax and duty and on top of that, have to pay a "processing fee" to the parcel company. There are ways round it but, if you're not careful, you can end up paying 3-4 times as much as the original selling price. If you want me to get the pipe for you, just let us know.
