I've also been impressed with the Casio's lately. Not the cheap ones at wallieworld, but some of the nicer ones have a decent feel. Used to be that Technics were a good brand too (for feel/price) but they fell by the wayside.

Personally, I like a weighted board for acoustic piano sound. That's it. I prefer the synth feel for most sounds. I have one Roland weighted action board (stage piano type board) and the rest I own are regular synth feel. I actually prefer a synth feel with polyphonic aftertouch, but that's just my view, and that 'polyphonic' aftertouch isn't so common anymore in reality..

I do not work here, but the benefits are still awesome
