i like the zipshot. use it with my canon g12. the shorter one.
it can move around a bit. for still photos i use a remote trigger, or set the timer for 4 seconds, if i'm doing along exposure.
but for general use, i don't worry about it.
you can 'wedge' it by splaying the legs a bit, as they do have some spring to them.
and i imagine you could hang a bag or weight on it if you could rig up some sort of hook.
