You are right, there is no way to give an exact purchase price for all of EU without a page long list.If you are in Europe, and purchase with shipping, your final price will vary with your country, since each country has its own VAT rate (and law says the destination country VAT is to be applied, AFAIK)
But in the Audiophonics ET400 review Amir wrote the vat included price, in this one he wrote the excluded price, so it's worth noting it will be a 20-25% difference.
