When my daughter transitioned from her 3/4 size to a full size, it took me about 6 months to find the right guitar. She didn't know how to pick a guitar, but the small guitar was holding her back. She said she really liked my guitar, which was a Ramirez 4NE. And she did play better on the full size instrument. But we are poor, hence the reason Dad is playing on an Estudio guitar.
Well, after about a half a year of shopping later, I found a Ramirez 2NE for 900 dollars used, in excellent shape, and with no discernable fret wear. I played it for about a week at my favorite local shop and decided to buy it for her. I had it set up through the shop as it was included in the price, and she now plays this guitar and loves it.. She has only been playing about two years. I think this guitar should get her through intermediate level.
One needs to take into account how much money needs to be spent, not what you are capable of spending. Even if I had more money to spend, doesn't mean I would have spent it anyway on her instrument, because it just wasn't necessary.
