I've had a few guitars, but never did much with them. I got a cheap electric in HS and tried to learn but gave it up, to hard. After getting bummed I played a friends guitar which was a little more expensive. Man, it was night and day difference. I guess what I'm trying to say is a cheap guitar is cheap and hard to play. Make sure you get a good quality guitar which sounds like you are.
I was also going to suggest getting a good teacher that is age appropiate. Sounds like that might be covered. I put my boy in piano lessons last year and it didn't last long. He was border line to young, but the main issue in my opinion was the teacher didn't know how to teach his age.
Also, don't forget accersories, tuner, case, etc.
And honestly, if you can afford to do this, don't buy her a guitar. Take her to the store and let her pick out what she wants. As said, fit is important. Theres a lot of fun going to the store and trying everything out and picking one for yourself. Go before hand and pick out a good salesperson that will spend some time with her. You can learn alot from a guitar sales person. Sounds like she could use a "me" day as much as a new guitar.
