My Looks needed replacements so I bought new Shimano 105s last spring and have been very happy with them. No problem clipping in or out. I can't comment how they function after getting really grungy since I use my rain bike when it is disgusting outside. I also bought Shimano PD R-540 SPD-SLs for about $30 at the same time. They are a low cost pedal that I put on my rain bike so I could used SPD-SL cleats on both bikes. The cost of the R-540s with cleats was a few bucks less than the cost of SPD-SL cleats by themselves . So, for about $100, I bought the 105 pedals, beater pedals, and two pairs of SPD-SL cleats.
