I'm new here, so what i'm going to say is "for what it's worth.".
I love Martins, so let me throw that out there. I do agree that they tend to come with some baggage. Of the 4-5 that I have owned, I've had to have 2 neck resets. My recommendation would be to buy them used, and well played. When you do this (of course), ensure you check the neck angle, and also ensure there is plenty of saddle left. I know I am preaching to the chior, but again, I love Martins. I also owned a 1991 SCGC, D model, and that required a neck reset. It was light as a feather, and played remarkebly well.....after the neck reset. I sold it to someone who could really play. That guitar deserved a better player than me. I've only owened 1 new Martin. I have to say that I didn't love it. Nothing wrong with it. I just like older Martins more. I own a 2003 D-28 right now that I bought for a song, but it needed much work. I have 1200 buck's into it now, and without question, it's the best sounding guitar I have ever owned.
I know my 2 cent's are on worth 1 right now, but this is just my opinion. Remember, all other companies copy Martin. This in itself say's something to me. I know the counter argument....they aren't what they use to be. I couldn't agree more. I wish I could go buy an OM-42, but that is way outside of my budget.
