Just FYI, I thought I'd share this keyboard stand with this group if you haven't seen it yet. It's called the Monolith by QuikLok. I have used nearly every stand on the market and this is now my favorite. It's one piece and it folds completely flat (the two upright sections swivel inwards). Sets up in two seconds. I have an older QuikLok mic stand that slides into the end behind the keyboard supports. It's extremely stable, there's lots of foot clearance for pedals and stuff, and it looks great on stage. Costs more than most at around $140 through places like Musicians Friend, but I find it worth it.
