Joby Gorillapod with ball head plate you may want this oneNever understood why they call this a GorillaPod, because number 1 that's not what gorillas look like, and number 2 gorillas are not known for gentle camera handling. But anyway, it's a GorillaPod, and you can put your camera on it. The included ball head has a quick release plate and an easy to use single knob locking system. Working well, with some cosmetic discolouration on the ballhead knob and one leg bumper.
