I finally decided to get the guitar I wanted with my 68th birthday this week. There's a great music store about 15 minutes from my house and they had over twenty Martins in stock so I could play guitars against each other. The sales person helped by also playing my choices with me sitting in front of him and listening. I went there wanting to try a D-28, which sounded really good to me. But ended up going with the OM-28 because it had more of the sound and play ability I was looking for. The OM-28 has a smaller thinner body, but a really full louder sound. It's similar to the 000 size and it's really easy to play. Every time I pick it up, it sounds like playing a dream.
