I have gotten rid of my clunky ELMO stand and document camera. I was happy 4 or so years ago to get it, but even back then the cart that I was given was never functional. It took up a lot of space and had very little storage and was not easy to move around. I always felt that the document camera and bolted on projector were wobbly and I can't tell you how many students disregarded/forgot directions, sat under the projector (which stuck out to the side) and then stood up and banged their head.
In its place I have an old (but very functional) rolling cart with 3 levels. The top of the cart is the perfect size for the Justand and my laptop. I have the projector and other miscellaneous supplies (pens, tape, etc) on the middle shelf and the bottom shelf holds all the supplies for the day's activities. With the previous arrangement all these other items had to go on a separate stand.
The Justand has been easy to use. I like the way the arm easily swings up or down and even students can put their iPad into the stand and take it out quickly. The iPad with the cover that we purchased doesn't fit securely, as the iPad would if we didn't have the cover or if we had chosen a thinner cover, but the stand holds it well enough that I don't fear that it will fall.
This arrangement makes it really easy to use the iPad as a document camera. I have been using the CamDraw app to annotate on top of whatever paper I am displaying for the students.
The Justand 2 looks fantastic as well, I have been using the original.
