Leolani have long been associated with the cheap and cheerful, highly decorated tourist ukes. They have, however, moved to making more legitimate ukuleles and both AJ Rafael and Prescilla Ahn use Leolani ukuleles. Just be sure you're buying one of their decent ukuleles rather than one of the junkers.
