I use my phone. I built my own "stand". I will try to explain it, but when I go home I will take a pic and post it.
I had a bicycle light that I was not using anymore. It had four rubber arms with wire inside them? Either way, the arms were designed to be flexible, but stay where you put them. I pulled the light part off, and zip-tied it to a golf shaft. It fits right in my bag. To setup, I just stick the shaft in the ground, and slip the phone into the rubber arms. Pretty easy.
