I've used the Shimano M324 pedals since day one on my commuter bike (January of 2008). I wear Specialized Sonoma shoes with SPD cleats for the commute, but can use regular shoes for local errands or when I decide to have lunch away from the office. They've been good pedals, they also look good on the bike and reasonably priced. Never regretted getting them.
