KoAloha started making ukuleles in 1995 and have quickly become very highly respected. There are an impressive number of top ukulelists using KoAloha ukuleles including Herb Ohta Jnr, Daniel Ho, Britt Paiva and Victoria Vox.
KoAloha ukuleles are all made of solid Koa wood (hence the name: koa+aloha=KoAloha) and built in their factory in Hawaii. As a result they are fairly expensive instruments, usually upwards of $400. They do also have a budget range called KoAlana which are built in China and finished in Hawaii. These ukuleles are in the $100 - $200 range but are hard to come by right now.
It can be quite tricky to get your hands on a KoAloha. From what I've heard, they're not easy to come across on the US mainland. Certainly, they're not easy to get in Europe. The Ukulele Shop seems to perennially have the, "Currently Out of Stock. Please contact us to order," sign up on its KoAloha page. But MGM usually has a good selection of them up on eBay.
