I got one of the engineers\mechanics where I work to make me one of these following the instructions on the "$14 steadycam" website. At works expense, of course
I shoved some blue paint on it (and some swear words in yellow, in the style of teamfishcake, of course!)
I haven't played with it yet, though....
The camera can be screwed straight onto the top, or the top of a tripod can be fitted.
