+1 on the A530's. I have M520's which allow you to click into either side of the pedal. I attached a platform pedal to one side of the pedal. This allows me to ride with my mtb shoes (spd) or with any type of shoe on the platform side. The A530 pedal was not around when I bought the M520's, otherwise I would have most definitely bought the A530's. It's the best of both worlds... a great pedal for a commuter. I do ride 90 percent of the time with my mtb shoes.
