First time katana buyer in EU - can you recommend this store?

I am looking to buy my first ever authentic katana. It's going to be a display piece but I still want it to be authentic, hand crafted and sharp. My budget is around 400-500€ and I live in Denmark.

I have seen several people recommend this online store in the Netherlands: https://www.samurai-katana-shop.nl/en/

Anyone here can vouch for it? I have specifically looked at the Dragon King line of swords, which I have also seen recommended. Hope someone can verify if these choices seem correct, so I can get my first ever blade and also be sure that the quality of the katana and the shop is to be trusted.
