I have a PKT-1 that I will never part with, it is an excellent ukulele.
I have almost purchased a PKT-6 twice, as I love six-string ukuleles, but as I have a custom six-string and a koa Pono tenor already I cannot justify spending the money (which I don't have unfortunately!)
Good luck with the sale, if I had the cash I would buy it in a heartbeat.
They do not make these anymore, and they are fine instruments!
