Don't get mad. I know that Mach3 is a dirty word around here. I haven't touched mine in about 2 months, since I finally found some DE handles at a local antique store. But I don't want to throw it out ... at least not until I collect some more DE handles. (It's the Turbo model with the vibrating motor. It gave decent results, prior to re-discovering wet-shaving and DE razors.) Probably I'll keep it in my locker at work, along with a tube of cream so I can get a quick shave when I need one. So back to my question ... are there any generic or non-Gillette blades that will fit? I see names like M3 and Matrix hanging up in the blade department, but I'm not sure if they will work. Does anyone know for sure which ones (if any) will fit?
