Anyone heard of A & B Supply? I got an e-mail from them, they are located just north of me in Marysville, WA, and say they are suppliers of laserable wood consumables. Looking at their online inventory much of it is what can be purchased at the local craft store, but they do have something "new" called rubberwood, but other than that the thin wood and the sizes of the wood are very lean. I'm waiting for my "registration" to go through to be able to see the prices. Meanwhile I'm going to e-mail them with some comments and questions.
