I don't know if this was a question, but I'll answer anyway...
Buy a DE and try it out for about two to three weeks, and if it's not to your liking just sell it again. You might lose a few dollars if it doesn't work for you, but you can consider it the cost of a life lesson. And if it does work, well... you'll probably lose more money.
Welcome, Kenny. You'll find lots of DE converts here, but the Mach 3 system isn't bad. I used it for years, and it's a little easier on my sensitive skin. I'm still relatively new to DE shaving, so maybe I need to continue to refine my technique and try some different blades.
