I Have gone from a S975 to PA 1000, my opinion remains the same: Home use, the S975. The Pa 1000 if you are playing out. Both keyboards offer a lot, and they are different. Out-of-the-box the S975 wins. The Pa 1000 gives me what I want as a Pro, but it needs to be personalized to WHAT I THINK is good. It is a great tool.
True happiness (contentment) in my opinion is to have both keyboards. My plan is to trade the Pa 1000 for a Pa4x, and buy whatever is replacing the S975.
