If I were to get a Martin for fingerstyle playing, I'd go with an OMC-Fingerstyle 1. They don't have a ton of unplugged acoustic power (not that you'd need it), but the tone is sweet and they play nice. Spanish cedar b/s and an Adi top, ooh la la!
Here's the one that Wildwood Music (near me!) has. I played it and I want it.
