I have 2 Prs9000 units. I gig with them every day. They are not that heavy to move around at all. I think alot of people are passing by a great keyboard by worrying about the weight. My old Mackie 450's and Jbl speakers weighed more then the 9k keyboard so do most KB amps. I use a Rok-n-Roller cart to transport my speakers with the 9k & X stand on top into the gig and then open my X stand and only have to lift the 9k maybe 6 inches onto the stand, thats it!!
