Thanks I'll check those out.One of the best places I can think of in NC is Muncy Winds, it's outside of Boone. It's about 2 hrs north of Charlotte, but worth it in my opinion. I don't think they carry Yamaha's, but they do have Selmer, Buffet, Leblanc and Patricola. The prices are usually good too.
My other guess would be Music and Arts in Charlotte.
