If you want an acoustic with beautiful tone, good sustain/resonance, and high playability, you may wish to try a Martin from the 000 series like any of these four. I played the EC, it felt great and sounded wonderful.
My advice is that you go to a luthier shop and try a few ones. One needs to feel the guitar, see how soft or tough is playing it, and above all, how one likes its sound. The Ovations play just OK for me, but I really didn't like their tone unamplified.
