I got the Gorrilla brand camera mount on clearance at Walmart for $18 if I remember correctly it was $20+ something regularly. It's a little noisey when you try to move it in really cold weather. The last time I used it was during 17degrees when that happened but otherwise it's serving it's purpose.It folds easily and stores in my backpack.
I'm not a proffesional videographer and just taking video of my hunts for myself so I could'nt justify spending more on a cam mount that would undoubtably be of better quality.
