I've seen a picture of what I want, but can't track it down anywhere...

It's basically a wire kind of stand - similar material and thickness as a bottle cage - that has two legs and hooks over the bottom bracket, with each leg pointing out and down perpendicular to the frame.

Saves leaning up against a wall, but is small, portable, cheap enough to have one at home and at work.

Anyone seen these before? Any idea where I can track one down? I've hit ebay and the like with no luck...
