Isn't Quilt Motion a Grace Frame product (or at least sold by them)?
Usable by Bernina (and many other) machines but not manufactured by them?
At least that's the way it looks after a quick look around at some sites and youtube videos.
Retail price is around $4,500 USD.
Call Grace and see if they have a European dealer.

eta: The dealer for Europe is located in the UK:
