How big are her hands? Fourteen year olds come in all sizes, from grown person size to little kid.

I recently decided my full-size guitar was not going to work for singing in church. I went to my local classical music store and bought a half-size classical by Austin for $125. Yes, it was made in China. I don't know what the top is made of. My friends are impressed with it (I haven't told them the price.) It stays in tune nicely.

I do use a thumb pick to get more sound out of it.

So if your student is small, she may like an Austin like mine.
