A simple camera arm is very easy to make if you have access to a welder. I have made several cameras arms and my first one being very sloppy but it would deffinetely work for a beginner and probably even a pro. But i've had more ideas and have built off what I made before and have made a light weight camera arm that can go at any angle and can hold a farely heavy camera.
If you have a light weight camera then I would say get a cheaper arm because they can get pretty expensive.
These are some of the things I have built.
This is my latest one. I call it the tank because when it folds up it looks sorta like a army tank.
Heres one of the first ones I ever made.
