I've been using KMC chains for a number of years with good luck. I've just installed the last of my spare 10 and 11 speed chains on my bikes. Now looking to get new spares it seems the KMC chains are quite a bit more expensive than similar Shimanos?
For example jensonusa.com:
KMC X11SL - 243g - $63
Dura-Ace / XTR CN-HG901 - 246g - $35
Seems like it used to be the other way around?
