If you are looking for your first acoustic guitar and/or you know that you'll be playing it very seldom then you should go for Yamaha F310. Not the best out there, but it plays quite nice and offers satisfactory comfort.
Great guitar when I started, still sounds fantastic after 5-6 years. Threw on some Elixers, would gig on it, if I hadn't broken it after exceptionally rough treatment.
EDIT: I threw some gaffer tape around the neck where it cracked, and a business card over a hole in the side, and on the old elixiers I put on 4 years ago it still sounds killer. Great for throwing in the car for travel, or taking a trip with friends where bringing out my expensive guitars probably wouldn't make sense
