You beat me to it, you tried the Casio. I think the PX350 is your best bet. Great keyboard feel and sounds, plenty of polyphony, on board speakers and a basic arranger unit for that sketchpad work at home. 1/4" stereo outs and ins.
I never use the onboard speakers but if I brought the piano into the house from my studio they would be useful.
