My favorite commuting pedals are the MKS lambdas. Here is an online review:

Review: MKS Lambda / Grip King Pedals

Mine have held up thru three IA winters and they still spin great. They are fine quality pedals that spin smoothly. The metal nibs are not too sharp. They have a built in reflector.

The best feature, I think, is just the size. They are not crazy large but they are wider than your typical pedal. Your foot never has to hunt for a spot on the pedal to push. The design just works.
