I bought mine two or three years ago direct from the manufacturer.
The price I paid at the website included all shipping and import to the UK, there was nothing else to pay. It came via UPS. There was a long lead time though, maybe four or five months, but I note that's dropped now.
However I think I might have been lucky that time. More recently I had a stock shipped from Canada. Value was below the £130? Duty threshold, but I got charged VAT and Parcelfarce's handling fee.
