Hi, Mats. I've never dealth with SW Fastener, but I've heard a lot of good things about them. I think they recently moved some computer equipment so they might have a backlog; be sure to ask them if you order from them. You might also want to try Baileys, a sponsor here on this site.
I've see similar questions from the fellows down under in Aus & NZ. The snag they run into are the taxes they have to pay on bringing in new saws. Also the delays & problems they run into if some falsifies a customs form trying to avoid taxes!
There's a fellow from Sweden who posts on another site; he'd probably be able answer at least some your questions.
Best of luck, & let us know how you make out.
