You can't really go wrong with Warhawk's recommendation. If you're hesitant about the cost since it's a bit of an investment up front for something you aren't sure you'll stick with, then there are some other options.
If you are comfortable with second hand, then ebay and the buy, sell, and trade forums are a good option. You can find nice mild superspeeds for about half the price of the DE89.
If you prefer new, then the Feather Popular makes a good, inexpensive starter razor. That was my gateway drug...
