Ditto on what everyone else has said. The only thing that I'd like to add is that my first and only DE has been the Futur. At a low setting, it allowed me to perfect my technique, and as I started getting better I was able to slowly open the razor. Now, I've gone from the Merkur Platinum blades to the Feather Platinum blades, and once again the Futur allowed me to increase and decrease the aggressiveness of the razor as I needed. Now, I've never used any other type of razor, but I must say that the Futur was an excellent buy for me. Still, if you prep your beard properly, you should receive excellent shaves from any of the Merkurs....just be sure to stay away from the slant bar until you have a chance to hone your technique.
