There's a recent post on Ponos, do a search.
I own a Pono Tenor cutaway with rosewood body and cedar top with pickup. I am extremely surprised with the sound, much better than I expected. I've played a few Ponos in the past and they were a bit soft. Perhaps the newer models with lightened bracing is the reason for the improvement in sound. The action is a bit high which causes the notes to be a bit sharp up the neck, but that can be fixed. The gloss finish was nice, the workmanship good, and inlays a nice touch for a $500 uke.
I opted to change out the strings to Savarez Alliance classical guitar strings, which added volume, clarity, and sustain for this particular ukulele.
