I have found that Shimano SPD M520's work really well for me, are cheap, and are just about bulletproof. No reason to switch to any other kind. They are on all 3 of my bikes, and have been on every bike I have owned since I went clipless about 7 or 8 years ago. I didn't vote in the poll because none of those apply to me. There are other pedals out there, but none work as well as these do, for me.
