here they are patrick. seems pricey but considering the price of lighting and space it's not that bad after all. I have lmited space and overspill is a problem
so this is worth a look.

Heres a dumb question. Do the use of the rings means no need for a green screen or does it just assist in defining the edges better with use of the rings? I told you it was a stupid question but how cool would it be if you could just snap on a filter or ring that would provide a green screen around the subject?

That would be cool. Its a combination of the light and the screen.
The screen is made if glass bead and the ring consist of LED's.
I'm going to investigate futher. I have spent considerable time lighting my green screen and let me tell you it is a chore.
here's another link.

You still need a backdrop - in this case it's their special grey backdrop.

Yup, It's a two product buy.

I checked this out at NAB last year. In more careful testing using the setup in their booth I found some major flaws in the key. The booth guy blamed this on a box under the carpet that needed to be adjusted...

The easiest ways to cure reflection from the greenscreen are 1) to increase the distance between the subject and the screen, 2) light the greenscreen two stops or so below the subject lighting, and 3) to use a non-reflective material such as the foam-backed greenscreen fabric sold on eBay. Total cost not much over $100 depending on the size you need.
