Hi all - This is my first post, but I'm a longtime lurker. Thanks in advance to all who can help me. I'm a high school teacher and I recently receieved a $20,000 grant to do an iPad pilot at my school. Part of the pilot will be creating a mobile lab with 15 iPads that teachers can check out and take to their classroom to use for lessons. The problem is that the $20k is less than I requested and I hate to drop a chunk of it on the Bretford iPad cart. I mean, it's pretty cool, but it's $1600! . I want to create some sort of DIY solution to store 15 iPads in a secure way. It doesn't need to have charging/syncing built in - I don't mind mounting a couple powered USB ports on whatever I find. I had a couple of ideas: 1. I could get two of these: and attach them to a cart. OR I could get something like this: and just have one drawer for each iPad. Of course, neither would be as secure as the Bretford cart, but they'd be significantly less expensive. When they aren't being used I can always lock them in a closet. Does anyone have any experience with this? Any ideas of how to store/transport 15 iPads? Thanks!
