[QUAD-L] Handle?

[Greg]

I'm trying to find a slip-on palm typing stick, like the (Sammons 
Preston Slip-On Typing Aid). Or something like this.

I had something like this on my camera mount to help me move my camera 
around. But when I tipped over, it broke it.

My camera is on a trypod head, with a small bar that sticks out the 
back. I connected the handle to the bar, so I can slip my hand in it, so 
I can move it around.

Anyone know where to find something like this that doesn't cost so much?

Thx, Greg
