It is not overly expensive but it is rare. My theory on it's rarity is there aren't many lumber importers bringing it in to the country because there is simply not enough other uses for it. I believe it is the absolute best wood to make a guitar from. The guitar business is actually minuscule in the grand scheme of things. For most similar applications Mahogany works just as well.
Mahogany is extremely plentiful readily available and very inexpensive.
For this reason very few companies offer it as a standard option. As of this writing I only know of several companies offering it. These companies are David Thomas McNaught , Gary Jacobs , James Jaros, JET , Heritage , Pagan and of course myself . So a very good investment would be one of those. Be extra careful these are total fakes.
