No idea if it's worth the price difference, but....Nato is generalized or locally used name covering various subspecies of similar large trees which grow mainly in South America & Africa ? said to be like a softer & cheaper form of mahogany (not related) ? often used to make necks & backs on acoustic guitars. Probably a sensible alternative to mahogany, which is said to becoming quite rare now in large useable sections (probably protected species in many areas) :-? .
