Operated by Hawaii Music Supply, this website has an incredibly wide selection of professional ukuleles for sale. In addition, they boast something not all online instrument retailers can: they have a Youtube channel through which you can hear each instrument and get an idea of its timbre and quality.
An excellent resource for beginning ukuleles and string accessories.
