This is an east coast based importer. There is no other Marstrom distributor in North America as far as I know. You can buy direct from Marstrom (http://www.sailcenter.se/) but I don't think it will be worth the hassle of working out shipping/import duty, customs etc.

Where on the west coast are you?

No clue about Javelin's.
