I used to use SRAM PC-970 chains and Shimano LX chains but recently switched to Wippermann chains. I was happy with the Shimano/SRAM chains until a week old SRAM PG-970 chain broke. I gave the Wipperman 909 a try, and have since replaced the chains on two of my other bikes with the 908/909 chains ($25-$40). For the money you get a smoother and quieter chain with cleaner shifts. Just remember to install the Connex link correctly, otherwise the chain will skip.
