I looked at the Luna line a while back and have been watching for the chance to get to play one. I like the idea of them being designed for women (instead of being a shrunken-head version of a "real" guitar) Besides, they're pretty.

My mother has a little Martin. The neck is about the same width as my guitar, stumpy, and doesn't sound very good. With new Martin's, the "new" smell seems to last forever.
I play a J-45. The neck on it is narrower than the 45 a friend has, so there's apparently differences in that according to year.

I'm routinely surrounded by about a half dozen Blueridge..and one of them sounds good to me. If you shop that brand, I hope you'll play it before you buy and listen to someone else play it too.

Not long ago, I wanted to experiment with different stringing and bought a Yamaha (full sized) on clearance. It took a couple days of playing before it got any music in it. At under $100, it's an excellent thing to play with, but if I was buying a guitar to really play, I would want a used one to save the aggravation of requiring set-up immediately (plus, I like the idea of guitars that are already full of songs)

If you resemble EmmyLou Harris in any way, it might be a good idea to consider getting one that you can easily play behind your back?
