I would go hang out on the AGF (acoustic guitar forum) too and ask your questions. Nothing against the advice here but give it a try. You can never have too much good information. Check out Frets.com too. In general, the challenge to a decent acoustic is the lighter the build, the increased resonance and volume (for a given body size). But as with most things there is a trade off, lighter builds and high performance usually means solid woods (as opposed to laminated) and with solid woods come increased care and feeding (as well as cost in general).
