If you're interested in Iaido, you can try the North American Sanshinkai (of which I am a member). The head instructor of the organization, Shihan Roger Wehrhahn, holds frequent seminars (depending on your location, this may be an option), and also recently released an excellent instructional video on the art- you can get that at his website www.mountainteachings.com (his seminar schedule is also posted there). Hope this helps...
