I like the HPL martins a lot but I know you would be WAY happier with the ones with the solid spruce tops. The sound is much more pleasing in the long run and the price is about $50 more. It's the best guitar $50 you will ever spend.
As to size it's a good idea to try the 000 sixe as well as the dreads. Both are $549 for the Solid topped models.
