A CoolerMaster QuickFire Rapid with MX reds is probably one of the cheaper good quality keyboards at the moment.
This; the QFR seems to be a Nordic version that will fit Norwegian, Danish and Swedish, it's the same quality as Filco, but cheaper as you won't have to get one from England, it's got media keys and a snazzy red plate.
As long as you don't mind the lack of a numpad that is.
If you need a numpad then the SS 6Gv2 is actually a great keyboard for the money as the blacks are also a linear switch, it's also available within your country so no shipping, and it's fairly decent quality. The only issue I've heard people have had with it is the keycaps, primarily the printing.
I think Ducky might have some boards available from Danish retailers, you should check
this thread for retailers. Again, if you want tenkeyless or another Ducky model it's worth looking through the thread to see if you can find any Danish retailers as they might have other Ducky models.
