+1 on the Shimano PDM324. Easy to clip in and out of - platform side has a nice ridged surface the soles of your shoes can bite into, and easy to flip from platform to cliped side. The one possible drawback is if you have a really wide foot, (like E or EE), they may be a little narrow. If you wear a medium width shoe; no problem. I also wear the Shimano mountain bike shoes with an SPD clip on my commute. No ratchets, velcro straps, or gold mylar embellishments - they just look like a pair of black walking shoes with laces - quick, easy, OK!!
