Hi Scott,
As you can see by my equipment post that I use a Quik-Loc stand, which is rock solid and quite rugged. It holds two keyboards and set up time is a few seconds. A spring loaded pin positions the stand and unless the welds break, I don't think it will collapse.

I also have an Ultimate Stand, one that also holds two boards and made from heavy-gauge aluminum tubing. Set-up time however, is about five minutes because every part must be assembled.

As for an attached mic, I don't recommend them at all. I've used them on both stands, and other than for announcements, they present problems. First, the mic must be switched off during performances because the sound of your fingers on the keyboard's keys are transmitted through the keyboard stand and produce the same sound that you would hear if the mic were on a normal stand and your fingers thumped against the stand--not good.

If you are a singer, as most of us are, and also a reader, the mic is never in the right position to see the music/lyrics and still maintain the correct position in front of the mic to provide good vocals. For that reason, I switched to a headset mic and eliminated all of those problems. You may want to think seriously about the headset mic instead of attaching one to the keyboard stand.

Cheers,

Gary
