Dave,
Yes, I have a S950, a PA900, and a MicroArranger. Sold my Tyros 4.
So far I am liking the PA900 and how easy it is to change just about anything you want changed. I'am about ready to walk out the door for my gig. I have a camera and tripod packed and hope to get some decent videos of the PA900 in action today.
