Hi 
For a while I've been pretty happy with my Varmilo VEM88 V2 with EC Rose switches.
I'm looking at getting some custom keycaps. Not many to find for nordic ISO layout..
nordic layouts are far more limiting in sets but there is still some sets out there. There aren't too many more budget oriented options that I could find.
The one that I would recommend personally is gmk norde, comes in a couple of colourways and should have the kitting, for a keyset it's expensive but the quality is extremely good (I have gmk on my mechanical keyboards and they are great)
You can get them here -
