The Re-entrants (my duo) have been lucky enough to get signature model ukes (they are brand new so not on their website yet). I've posted a couple of videos in
this thread
Obviously I'm biased, but of course we wouldn't have wanted signature models if we didn't like them! Ours are based around the Oahu Koa model ukes, mine is a concert, Ian's is a Soprano. Ours have black binding, rosette,headstock facing and tuners, with the band logo inlaid on the headstock and our respective signatures inlaid into the top, above the soundhole, and Fishman passive undersaddle pickups.
We've found them to be very well made (the production models too, not just ours), nice players with very slim necks and typical 'koa sound'. It's awkward, and oviously I would expect people to think 'he's got to say that' but we were honestly very impressed with them at a couple of trade shows, which then lead us onto the signature models.
They are not that common in the UK at the moment, but as they share a sidtributor with Kala, they'll start popping up all over soon, and of course shops who stock Kala should be able to order them in.
