I just got a D49SPK off Ebay and love it! It has a rich sparkly tone with amazing sustain for an all laminate acoustic. The inner ply is plain maple and the center ply looks to be the same, as plain maple is plentiful and inexpensive. I like the brown Abalone binding alot and the gold Hopi binding on the top. I am using D'Addario Flat Tops semi flat phosphor bronze 12-53 strings as I like a warm sound with low fingernoise. You may want to try those or GHS has some great strings as well. The heaviest gauge I would go with is 12-53 or 12-54.
