Keep in mind that Mike is a genuine custom builder. He will work with you on decisions about all the aspects of your ukulele, from the number of frets to the amount of bling. I have two Mya-Moe ukuleles and love them, so I say this not to disparage them but to explain their business a bit, but Gordon has said that MM is not a custom luthier (although it possibly is for some musicians) but is instead a made-to-order builder. That is, there are certain things you can choose about your Mya-Moe build (wood and binding, headstock, strings, tuners, and even neck width) but there are other things that are simply non-negotiable, like bracing, body shape and dimensions, number of frets). Here's Gordon explaining this in some videos:

There's absolutely nothing wrong with Mya-Moe, as its six plus month wait list indicates. If you want to be involved in the specifics of the design of your ukulele, I'd recommend a luthier who does that, like Mike. If you like the Mya-Moe sound, want a Mya-Moe uke, and want to choose from among some of the most beautifule soundwood pieces in the ukulele universe, and you don't want to be involved in the engineering specifics of the design, then go with Mya-Moe and you won't be sorry.
