fungusyoung said:Not trying to discourage your search for an M20, but if an M30 is what you're after... try a Martin 000-15. The new ones are now made of all sapele, but mine from 2003 is genuine mahogany. Not exactly sure when the change from mahogany to sapele was made, but it must have been recently... nor do I know how different sapele is tone wise... it's said to be in the 'hog family. Anyways, the 000-15 is an amazing guitar, and my pick for best value in the Martin line up... it's also within your range whereas even if an M30 surfaced, I doubt it would be.
FYI: Kind of a crummy shot of my 000-15
Good luck!
Be forewarned about the 15-series from Martin. Every one I have seen, the neck lifts up after a while, raising the action, and making playing very hard. Something about them, I don't know what it is. They sound very good for the price, and seem to be very popular, but like I said, after a while, maybe a year or two, the neck bows up.
A neck reset is in the works for one of my students. The job is equal to what she paid for the instrument.
