You can only have two.

First: +1 on the B&H (Blazer and Henkes). Desert island guitars, to be sure.

Second: responding to Frank Sanns' post from last year (!) about the D size:
Last summer, my nephew, who is a fine guitarist versed in fingerpicking, jazz, and more, visited me for the first time. I brought out the highlights of my guitars. I began with the Collings D2H. Next was the OM1A. He said (not exactly), "Why this guitar size? What is the point?" He had ever seen/played only dreads. He struggled to wrap his head around it. Next was the B&H OM-28 style. That began to draw him in, and he returned to it later, given the opportunity...

I think he began to see the possiblilities...

Right now, my 2016 D1A and my '57 D-28.
