It's really a shame the Yamaha DGX650 is not a bit lighter and little narrower to carry around. It has everything you would want. A great action, great CFIII concert grand piano voice. 128 note polyphony. Styles quality from higher up arranger keyboards. Great additional sounds such as guitars, strings, brass, etc. Audio input for plugging in a mixer with mic or using just plugging directly in a iPhone, etc. to play songs. A USB input for playing and recording .wav songs or recording anything you play or sing into the keyboard. Internal speakers which can be shut off or kept on while going into an external sound system. I just wish it wasn't around 35 lbs and just a little bit thinner. It would be the perfect $799 gigging keyboard.
I sell the Privia PX350 and my few gripes would have to be that the styles themselves are ok but the drum kit sounds are just not up to Yamaha or Korg quality still and I wish the strings were better. Everything else as stated is a real plus for something small and light enough to carry around to jobs.
