go to the martin website and see how much you have to spend before you get anything other than black richlite fretboards and bridges, seems to be around the $2300 mark at the moment. When it was introduced it was only the below $1000 x-series, but now its a proven material, gives consistent results and is more plentiful than any alternative they seem to be pushing it up the range. they even sometimes call it 'FSC® Certified Black Richlite' which i guess means even the paper its made from is sustainably sourced
but martin have been happily incorporating alternative materials and construction for a good few years now without too much fuss from anyone . i think there HPL back and sides feel quite plasticy and the multi lam necks look like they come from ikea. But the tone of a martin still comes mostly from the solid spruce top. This makes even the cheapest ones nice sounding players instruments, if not quite the more refined appearance and tone of an all solid wood handmade acoustic
