Kanilea Ukuleles are a Hawaiian company run by Joseph and Kristen Souza. All their ukuleles are made in Hawaii and you can take a tour of the factory if you happen to be on Oahu (you can find out more on their website).
More recently they've come out with the entry-level Kanilea Islander range which has been getting excellent reports.
