I was also worried about commuting and went with the Cheap Forte Campus peddles and a low end pair of shoes to make sure I was happy. I'm totally sold on them for Sunday rides now. I LOVE how much more power I can put into the peddles. Still don't like the idea of commuting in them with the traffic I have to navigate so very satisfied to have the platform/clipless peddles. I'll upgrade to a better set for my main bike eventually and put these cheapos on my Mountain bike.

Picked up a bike yesterday that has a set of Looks on it. I was hoping there was a Cleat that would fit my SPD shoes but it sounds like I am SOL and have to get either shoes or new peddles.
