Caviat: I dont' play an instrument, so take that as you will.
I'd go for a Parker Fly, based solely on the opion of friend who does play, and who's judgement I trust in this matter. And, I like the look, and the tech behind the instrument.
Of course, my preferred instrument is a direct neural interface that can caputre what I play while in REM sleep.
When you dream, people can fly....
