Re: Guitars for Mommy!
PRS makes wonderful instruments if you can find someone with a good selection of them.
Fender generally puts out a good instrument, a Mexican made Strat is still a very formidable instrument in most situations.
I'm down on Gibson because of a friend who bought a 8k arch-top jazz guitar and the pickups came wired backwards, I think that epiphones play better for the price.
Best way to handle it would be to go with her and get her to choose the guitar she really wants. It is really all about the player.
