I visited a store and looked at PSR2000 and I was impressed with the fact that the layout and organization of the keyboard was greatly imporved over PSR740. For example, now there is a dedicated buttons for TEMPO and so many other things. The voices and drums are good like PSR740. I did not play with it for long time. I am wondering is the speaker on PSR740 better than PSR2000?

Casio MZ2000. Nice keyboard, lot of buttons and sliders. I did not get the chance to play it well... only one drums and few voices. The Grandpiano 1 &2 sounds were not that good. Certainly I need more time to examine other voices and look at styles.
