What razor do you use?

I sort of mean this as a guy question, but since women use razors as well, come one come all!
Anyway, what razor to you use. Brand name (I use Fusion), generic type (straight razor, electric), whatever.
Equally important-Why do you use what you use? (I think Fusion blades are really sharp when new, and I think it looks cool. But they are really expensive. I could be persuaded to change).
