TriDevil - I bought Look A5.1 pedals off of e-bay about a month ago. I've got a couple hundred miles on them so far and think they are great. I switched from SPD pedals to Look. For me the Look system provides a better platform and in general I feel more connected to the bike. I love the adjustable float option, although it took sometime to break in the pedals to the point where I actually noticed a difference. One suggestion, start out with the release tension low until you get used to the new pedal system. Even the lowest tension setting was more resistance than my old pedals provided. I made the mistake of starting out with a high tension and had a minor mishap trying to clip out on my first real ride.
