I have the SL-CR's. Also, I've had 2 knee surgeries (ACL reconstruction & patellar condroplasty) in the last 3 years and I have no knee pain, commuting 5 days a week (~80 miles total riding/week). They're in the $60 range I believe, and they seem alot nicer than the shimanos in that range IMO. There is a rider weight limit on some of their Ti pedals, but we're commuters, who's going with Ti pedals?
