You can try Kaye's Music Scene in Reseda. He has Kala and Kanilea and was talking about carrying Kanilea's lower end line, Islander. Nice guy. He was excited about Islander ukes after seeing them at NAMM and he had a good section of Kala last time I was there. A better and more interesting selection would exist at McCabes in Santa Monica. It's a few miles (8-10) down the 405 freeway, which can be quite busy at times, but worth it for the selection, imo.
