like everyone else has said, martin, maton, takamine and cole clark are all quality instruments although they are on the pricey side, if it is your first acoustic, i'd suggest a low - mid priced epiphone.....
i still have my first epiphone acoustic, and although its not a high end guitar it is a joy to play, just play a few before you make your decision and check the action on such a guitar, although it can usually be corrected witha good truss rod adjustment and a bit of a file down on the bridge......
happy playing
