If you like the Guild, stick with it. If you want a new guitar, there are a lot of popular names out there (Alvarez, Gibson, Fender) which probably can provide you with different varieties of guitars, electric or acoustic. I own a black Alvarez acoustic and a Gibson electric, although I'm looking to shoot for a used acoustic/electric hybrid. See if you can get a used guitar. You'll get some nice deals and normally the guitars are nice as well. Since you're probably looking for an acoustic, try an Alvarez.

Although this is a bit superfluous, the best of the best are made by people you've probably never heard of, for example my uncle has a "Paul Fischer" that's worth somewhere between $10-15k (he's a professional classical guitarist). I know that's obviously not a choice, but as you can see guitars can get mad expensive. Good luck with your search!
