When buying an acoustic guitar, you don't have to worry about all those extras. You just have to worry about finding something that feels and sounds good. Keep in mind that you can always buy another guitar later. Once you've been playing for a while, you'll know a lot more about what you wan't, and you'll be able to choose more wisely.

Just don't be afraid to pick up the most inexpensive (no name) model that the store has to offer, because it might be what you need. I have a no name acoustc guitar that A friend of mine ordered from QVC, and its very special to me. Its my recording guitar, it sounds very clear, and most importantly its very comfortable.

Good luck...
