I'm trying to make a purchase decision between the PX-350 and the PX-5S. I'm mostly looking for a great piano sound (that the 350 has), but am excited about the PX-5S. Not very much more money for better Rhodes & Wurly sounds, effects, and more controllers. However, I'm not quite sure what piano features I'd be missing by going with the PX-5S. Does anyone know how the piano experience is different? (Are they identical?) I think the PX-5S doesn't support half pedalling, but are there any other differences in sound, features, keyboard feel, etc.? Thanks for your input!
