If your not sure an easy way to start ( many here would differ) is with a good Shavette. A Parker or similar design. It uses 1/2 blades. You can either buy the 1/2 blades or cut the DE's in half.
The easiest and least costly way to go. But, a great shave.
If you enjoy it. Next would be the Feather Artist Series with a Proguard blade. More money but a great open experience. Then on to the Straights.
