Hi Scott,
It doesn't take long at all; it's only 3 pieces at a time depending on the size of the gig. For most gigs, I only use the smaller PMP2000 and the PR10's. For larger gigs the PMP1680s and the PR15's.
I also just purchase the Apex AX90R keyboard stand:
http://www.ultimatesupport.com/product/AX-90RI get so many compliments on that stand. It's a breeze to setup and it's steady as a rock. It is a little heavy, but it's worth it. The RED color really adds POP to the stage.
I'll try to take some pictures after next weeks Wedding.
