Hi, I'm a newbie. I've owned the KAWAI VPC1 & have been playing a borrowed CASIO CDP-120. I can say that I much prefer the CASIO for the feel and integration with Modartt's Pianoteq 5. I am waiting for my new CASIO PX5S and expect it to be even better feel and integration wise due to the fact that it is a new action, transmits note off velocity and uses Hi Res MIDI to boot. I hope to post a further comparison when I have auditioned the PX5S. Kindest Regards, Chris
