Anyone used Chromatte (Holoset)?

I'm looking into a good chroma solution for portable keying. I am currently demoing the Holoset which is really cool! The only thing I'm thinking is that for the price ($2,400 for the lite ring and 8'x8' backdrop) you could buy a lot of lights and backdrop. Also, if you're shooting with two cameras, am I correct to assume you would need two lite rings?

Has anyone used the Chromatte? What are your thoughts? Any other suggestions?
