Most music stores carry ukuleles these days. Some have good selections and others not so much. If you are just starting out I recommend going somewhere they actually know about ukuleles and can recommend one to fit your needs, or to take someone along with you who has some knowledge. Here are a few locally.
Kansas City, MO
Charles of Squirrel Manor. Independent dealer Chuck is a Ukester and sells out of his home and is quite knowledgeable and best of all honest. He carries Eddy Finn ukuleles, a good medium priced ukulele and has recently added PukanaLa Ukuleles to his inventory. Along with numerous accessories including Aquilla strings and his own invention the Uke Thong (a ukulele strap) Chuck is a "one stop" shop.
Contact Chuck: email@example.com or talk to him at a Ukester Meeting.
