I just switched (like this week) from the Look Keo Classics to Speedplay zeros.
At first I had the float way high on the Speedplays and did not like that at all. I've turned it down to almost zero and like that much better.
Once you get used to it the speedplays are easier to get into. The reason I switched was for two sided entry. Tired of kicking the pedal to get into it at redlights with cars behind me.
both pedals though are great.
The zeros are only like $10 more than the light action speedplays. I actually paid less for my speedplays than you posted for the Keos, and that was at my local shop.
