I thought I would get back to this thread and report what I finally have done. I spoke with several folks about the PA900, BK-9 and read all the posts here. I thought about what was the main problem with a heavy keyboard and that was setting up and taking down at my house every day. So, Sunday I will pick up my 2nd Tyros 4 from a very good friend and have one that will never leave my house and one that will always stay in the gig bag. I think this will help a lot and hope for the best.

Thanks to everyone for your input, including those who took the time to send emails. Your input has helped.
