just search for the gear you are looking for at http://geizhals.eu/ - it lists a lot of online stores and prices (both with VAT and net of VAT). plus rating system for shops. I will happily buy from any store with a rating of 1.5 or less (1.0 = best possible rating). It is also indicated, if a shop delivers internationally. If so, they will all sell to any corporate client within any other EU country (= including Denmark) free of VAT. You just need to provide your European VAT ID-Number with your order.
I know, but often, even though they deliver internationally, they either don't have the Vat input field or require a bank transfer payment in order to deal with the price without vat.
But I'll have a look at that link, thanks.
Edit: Having browsed through a lot of those... I couldn't find one with a vat input field
