I've got way too many ukes, but I have a semi-vintage Kamaka and a Moon Bird that tie for "favorite uke". The Moon Bird is...well its a Moon Bird, so it is awesome from sound, to tuners, intonation, action etc. The Kamaka is an Ohta San from around 2000, so not truly vintage, but it is older. Before I purchased it, it had been updated to Goto UTP tuners. It's a joy to hear and play, and it has a richenss to its sound not found in any of my new ukes. Now a really vintage uke, like an old Martin would be awesome, but I would be awfully afraid of damaging it! That said, next time I see a nice Martin tenor vintage uke come up for sale, I might just snag it! I really didnt get the whole instruments opening up with age thing until I heard some older ukes side by side with newer ones (an old 60s martin side by side with a new Martin). The difference was amazing. I've been tempted a few times by older Kamakas, but have yet to find one in good enough condition for the asking price. I dig the old Tikis, though.
