You pay German VAT. The German VAT was already included in the price I gave you.
If you have a UK VAT number you give that to them, they run it through their special VAT Number cruncher and if it shows up as genuine then they ship to you without any VAT at all.
Yes, you get a Euro plug, but it's only a Euro plug to a figure of eight lead. A UK plug to figure of eight lead costs about a quid, and I'd be surprised if you don't already have a dozen around your house already.
Other than that, in my experience, the German model is
exactly the same as the UK PAL model.
