this is 1000x better then a handle, a handle will barely stabilize your footage, it will mostly just make the camera more comfortable to hold. With the glidecam you get steady shots while skiing, walking, running, etc.
I have one and although I'm still learning, its already made my shots incredibly smooth vs. my handheld shots before I got it
thats a glidecam 2000 pro. not DIY. i just bought all the parts for one today. im gonna try to make it tomorrow. ill probably post somewhere how it goes
