try The Kiyota Co. They don't have a website but can be reached at 410-366-8275 or faxed at 410-366-3540.

The Academy of Karate, Martial Art Supply Store for inexpensive equipment. You have to bear in mind though that you are getting what you pay for. If you buy a $7.00 bokken from them, that's exactly what you get, but it's not bad to start with
