I found a cabinet wood suplier here in Southeast Texas named Acadian Hardwoods for my supply. They have walnut, zebra wood, bubinga, bacote, cocobolo etc. Most all of the popular ones and many more (leopard wood, wenge, purple heart). Call some custom cabinet makers from the phone book and they can tell you where to go.
Bubinga is durable riser wood and less expensive to start with. Zebra wood is a step up in price which I think is beautifull. Some of the most exotic woods are oily and can be harder to finish.
I got some hard maple for laminations because it is economical and mostly clear of blemishes. I plan on getting some vertical laminated bamboo flooring to use for lams soon. You can get a box of that at most any flooring store or online.
