Have you tried the new Gillette Fusion? I admit I am a sucker for these new razors. But I don't see why anyone wouldn't updgrade. They basically give you the razor, and the new blades look like they cost about the same as the Mach 3 blades, at least at my local store.
Anyway, I have been getting a great shave with it. The only thing I am still having trouble getting used to is that single blade on the back that you use for sideburns, etc.
I would love to hear your comments--
