Most all low cost acoustics are made in the Pacific Rim. There are many companies that produce quality instruments from Japan, Korea, and God Forbid, China. (Why don't we just give the country away to them)! Acoustic Guitar magazine web-site will give you reviews of low-cost acoustics. Remember, you will not get solid sides and even solid backs normally at this price line. This will give you a "tin" sound without much bass and lower mid-range sounds. HarmonyCentral.com is a great site for reviews of more guitars than you will want to see. But, once you have decided on a couple, check out this site for reviews of actual purchases and the reviews of the models
However, Alvarez Regent series makes good acoustics in this range as does Yamaha and Fender. They, however, are mostly produced in the above mentioned countries. The best advice I can give you is to find a guitar store in your area, Guitar Center if possible, where they have a wide selection of guitars. Play them, as many as you can because even the same models will sound different. Then to save on the taxes, negotiate a web-site price including the tax. Check MusiciansFriend.com, Music123.com. The guitars will have customer reviews with the listing.
Good Luck! :)
