May I suggest an Ovation? Not a traditional acoustic, especially with the roundback and all, but I have this awesome Ovation Celebrity acoustic/electric and I freakin love it! Beautiful action and really fun to play.
The roundback takes a bit of getting used to as it tends to slide down your legs when you play it but once you get it its easier to play. Also, since this model has really un-orthodox soundholes, some of the highs and lows are different than a tradition centre-soundhole guitar but try out an Ovation when you go to the guitar shop. Mine cost me $900 but there are others that can run for as little as $349.
