Hey Ray, it is true that most of what is available these days is African Mahogany. I’m not a fan of African Mahogany as it is very grainy, and you never get a good smooth edge like you might with Walnut or Maple. One of my favorite woods to cut to replace Mahogany is Saplee like John mentioned. But you have to pick out your boards as it will vary in color. My advise to you is go over to Woodcraft and find something that appeals to you keeping in mind the the more exotic the wood, the harder the wood will be to cut.
i used to get real Mahogany when I was a member of the local woodworking club. We had a member who owns a professional wood shop. Occasionally a truck load of scraps would show up at a meeting and I would pick out the Mahogany. Some of would be red. Those were the days!
