I've been watching all the threads about various stand/mounts for my Ipad 2 and came across the Talent IMS-1 stand. I've been using this for about a week and love it. Super easy to use and inexpensive. I highly recommend it.
Here's a link. Be sure to watch the video.
Talent iMS-1 Music Stand Clip for Apple iPad (1 & 2) 233-048
I am using it on a Euro Boom microphone stand from On Stage Stands. My neighbor gave me the stand for free so all told this was less than $25 for me. The mic stands are easily found for less than $35 shipped. This stand is sturdy enough that the boom can be all the way out and still hold the Ipad at the end without gravity pulling it over or the boom going down.
Not only does it work as a floor stand, but I can clamp it pretty much anywhere (including in the car).
I am not affiliated with the makers of this stand.
