Have a look at the Shimano M530 pedals. The get a very good review ( http://www.bikeradar.com/gear/catego...il-pedal-45093 ) and supposedly are easier to clip into than the M520's. If unclipping is a problem, consider using the SH56 multi-release cleats, which are supposed to give more means of exit that the standard SH51 single-release cleats.
