Oh man, this is a great deal! Bought the same one a couple months ago new for several hundred more. Sweet tone if a warm sound is your thing. Sound board is very responsive. A good master luthier buddy of mine who makes customs liked the sound too... of course not as much as his own pieces, but a comment like that coming from him is quite a compliment to Pono.
Having had ukes come in and out of my possession and having had to do fret filings on several of them, I really appreciate that you can adjust the relief on Ponos.
