Look for one of these - around $30 - (typically branded "Polaroid");

They are made of steel with little "click-stops" at the hinges to hold the folding parts in various positions, and have a molded plastic grip under that vinyl wrist pad, which makes it comfortable to hold for a long period. It also can be converted to hold two hotshoe items at once with the included extra hotshoe adapter (in case you go all video-pro with a mic and videolight). Very surprising little device, particularly when compared to "flip brackets" from bigger names!
