Hardware for your front door is like jewelry for your outfit: It makes a statement, a first impression.
First, find a local store to visit; that way you will be able to touch and feel the weight of the hardware in person. If something feels too light (or cheap), you probably want to skip it.
To select a style, consider the style of your home. Is it traditional? Contemporary? Ask an associate at the store for help identifying hardware that might compliment your space.
Then you have to pick a finish. Consider the color of your front door. You probably don't want brass if your front door is bright yellow, for example, and you should be careful about choosing an antique bronze on a dark brown door. A good trick is to match the finish to the finishes of light fixtures by the door.
I would also change the hinges on the door to match the finish you are selecting.
Here are a few examples from Ultra Design Center in Denver: They have great finish options and a wonderful feel!
