Which cDynamo stand should I use?

We’ve got a few iPad Air2’s set up with the fantastic cDynamo swiper case, and we love them!

Currently, they live on little ipad stands like this.

It’s not a great solution, but it allows the staff to use them from a standing position, but also pick them up to hand to the customer to sign.

I like how the cDynamo has VESA mounts on the back (100mm sized), but I haven’t found anything to use yet. We would need something that is solid, but easily removable to hand the ipad to the customer.

Has anyone found anything that works?
