Ukulele factories on the big island?

Hey Hawaiian experts!

My sister is visiting the big Island next week and wants to find a uke factory tour or just a great place to find a ukulele. All I know of is Hilo Guitars for her to go play a bunch of different ones. I don't believe there are any factories that are tourable on that island though. Thoughts?

Here's an old thread on this topic:
