I'm going to second both of these stores! I think that Chuck's (or Washingtoin Music Center as it is also known) is the nation's #1 Taylor dealer. They typically have 175-200 (that's right nearly 200!) Taylors in stock at any time and their prices are a little better than Appalachian. Appalachian is a small shop wit a 'down home' feel, excellent, knowledgable staff, but limited stock. WMC has great staff, excellent service and a killer selection. It can be a little hectic there (especially on a Saturday) but ask for Brian Meader, he'll treat you right.

P.S. Mention my name...I'm collecting 'brownie points'. When I get enough, I'll get that 'free' PS Koa I'm dreamin' about
