Got a chance to try this out at the DC conference. I only played it for a few minutes, but it seemed to play very well. I would agree with the previous comment that it felt very light and responsive. I couldn't really comment on the sound, as the room was pretty noisy, but I was pleasantly surprised. I will mention however that I felt it was more difficult to hold while standing than a standard "top valve" model, although this could've just been me.
