I too use KMC pretty much 100% just because of the value they have IMO. I get them on Ebay from a shop called "trail this" been using them for years, great prices, faster delivery and never worry about getting a fake anything.

I have zero to with this shop I think located in WI, but been a very happy customer of theirs for years now. Other stuff they sell is very hit and miss but chains, that is my go to place. And if you don't mind the bulk packaging instead of factory packed box you can get them a bit cheaper yet.
