Dave,

Looks like you got it all figured out. The only thing that's left to do is begin developing more upper body strength. Then, lugging around the PSR9000 won't be a problem. I've found that laying on my back on the piano bench and doing 20-30 repetitions of the keyboard press helps a lot. I don't know that pressing my keyboard has may me any stronger but after lifting it 20-30 times I don't care whether I drop it or not. Hope this helps.

Steve
