Casio has a new Privia PX850. It is pretty amazing! 256 note polyphony, Ivory and Ebony keys, adjustable Hammer Response which controls the time deviation between when a key is pressed and when the note actually sounds, string resonance which allows the undamped strings to resonate when other notes are played, lid simulation adjusts how sound resonates in accordance with the opening state of a grand piano lid, 2 track recorder, audio records a stereo track as a wave file on USB device plugged into keyboard, loud built in speakers and best of all a price just above $1,000.00. Watch some of the youtube videos of players reviewing this model. You would have to spend thousands of dollars to get something close to this new model.
