I think you have to figure out the Pounds to Euros conversion first.

US dollar to Pound Sterling is about $1.50 (US) to 1.00 (Pound).

However, you have the VAT tax, and prices are generally better here in the US. So, your conversion factor is a bit off. (It's more like $1.57, I just checked).
Yup, my bad. We don't use the Euro in my country, we use Kroner. And it's 500 dollars, not 600, my bad.
