You obviously didn't read the thread.
Generally speaking EU prices include 20% VAT and then the usual translation for consumer electronics is not base on the dollar-to-euro exchange rate but basically 1:1.
So if $500 is VAT inclusive that's 500=price*1.20 so price=500/1.2=$416
no, doesn't work that way most of the time. At least in my experience.
US$500 (without VAT) = €500 (with VAT)
