Ayers Guitar Company makes the Big Island Ukulele Co. ukes, Moku Ukes, and builds ukes for eBay Power Seller "taisamlu" as well.
I've owned both Big Island Ukes & Ayers ukes - same nice rich tone, however, they lack in projection. Really nice Koa. I did have the privilege of trying the new Big Island Mango Tenor and it had a surprisingly loud voice with a nice warm tone. I believe that Ayers offers various tone woods as well.
Check out this cool Ayers Koa/Mango Tenor:

I like Ayers ukes!
