I like Σ, but on the other hand it doesn't make sense marketing wise so i vote for 12 (good job kondiomir).
I agree, at this point I'm so used to the sigma symbol, but when I think of magi, middle eastern mysticism comes to mind...
How long until this poll is over? I'd like to make a submission , but away from my PC for the night...
I like Σ also. Is this poll finished already?
