Crafter's have plastic parts - tusq (fake ivory, coz like the real stuff is illegal) is what the top end brands like taylor use - but remember acoustics are not electrics are really need pros to do any mods to them.
Frankly, a crafter d6 is a good bottom end of good acoustic and has a solid spruce top (which is the most important part tone wise on an acoustic - the rest like back and sides and bridge is much more subtle), so I wouldn't worry too much about it. You should be able to get a good tone with decent strings.
