Yeah Betafon is an option, but It's not much stuff they've got left... And as mentioned the assistents are newbies...
There is a way more assorted dealer i Frederikssund (a city located on the mid-northern of sealand, it lies just prox. 10-20km north of Copenhagen). It's were I got all my new stuff from (Mediator, Interfaces +more), They also sells new programs for the Amiga...
But you've got to be aware that most of the hardware is not in stock and has to be ordered, I know he had quite some programs in stock.
But check it out on the web:
Kiwimultimedia.dkIf you want to call them remember the +45 infront of the phone number...
I think there is another store located in Jylland but I'm not sure on this, but That's irrelevant if you're only going to Copenhagen.
