welcome frohmanj! enjoy the bike when you get it. i had to reread your post cause i was gonna say since you're already in GER you should just get Hepco/becker which are made there. then i realized you mentioned price so assumed you were talking about them. LOL
I have a set on order (brackets were backordered from US distributor), and from what i've seen in my mind they have the best fitment.
i was originally looking at viking hard cases but from the reviews i saw on here you had to drill holes yourself, i'd rather have something that was 100% ready to go and not take a chance on making a mistake on install (even though i'm handy)
but whatever you choose, enjoy the new ride!
