I don’t like any logo of the suggested.
Here is a simple proposal: https://picasaweb.google.com/lh/photo/Ns8fhSWnpeh0Hdm6rgum5g?feat=directlink
I particularly like the first logo to use the "Sigma" idea. It's simple and direct, but the Sigma conveys an interesting double message. I would perhaps like something a bit brighter, though.
