Taylor and Martin are both a very good place to start with expensive guitars. Collings are superb. Some other wonderful brands, mostly already mentioned, are Larrivee, Santa Cruz, and Bourgeois. Then there are the handmade guitars by various fine luthiers, of which there are many. My advice is...play a bunch of different guitars of good makes and listen and feel what each is like. You may want one with an electronic pickup system too...it can be quite handy.    You'll eventually find one that sounds right and feels right, regardless of the name on the headstock. Don't buy it right away. Go away and think about it for a day or two. Then come back and try it again. Then go away and think about it. If you play it a 3rd time and hear something in you say, "this is the one", then buy it.

And if you want to be in a lower priced bracket, I highly recommend Yamaha guitars. They are a great deal for the money.
