Custom Loop - Where to buy?

Sorry for English, recently moved here and Swedish is terrible still!

3080 FINALLY on its way and thinking of doing a custom loop in my ncase m1 and when doing research realised I have no idea what vendors are decent here in Sweden, so after some recommendations of where to buy kit or are most places decent and just buy from cheapest after a Google (there were always avoid!! places in UK )

Yeah I already got screwed by #brexit with shipping some of my own stuff over so will avoid.

Thanks for suggestions, I didn't realise that EK could be purchased from directly in EU without customs, good to know
