There are some great choices in the sub $1000 range out there. Perhaps too many. When I've shopped for under $500 acoustics, the Guild guitars between $550 and $950 were awesome, but just out of reach. Take a quick look at some of them that my local shop has: http://www.dannyd.com/guild-1/

My other suggestion comes after I bought a Talor GS Mini. This little $500 guitar has a big, clear and very warm sound to it and is the easiest to play acoustic I've ever touched. If you have a Taylor dealer nearby, try the GS Mini out. I love mine so much I'd consider buying another Taylor, which for some reason, I never had an interest in before.
