The super-nice folks at Mya-Moe build some of the most remarkable ukuleles I've ever seen. I don't own one (yet!) but strummed a few at the Wine Country Ukulele Festival last year. Mya-Moe ukes are so light I'd wager you you could suspend one in mid-air with a mylar party balloon. It's freaky. They have a great website (the only ukulele builder site I know that posts the daily lunch menu) and are worth following on Facebook, YouTube, and Twitter. Be sure to watch their weekly video posts on what's happening in the shop. Here's one in which Mumford & Sons stops by for a visit.
