I need a new chain and was looking for some on ebay. I'm looking at a x-ring or z-ring chain. There are so many manufacturers. Are there any chain manufacturer to stay away from. The ones I looked at were Renthal, RK, EK and D.I.D among others. I was recommended the D.I.D. one but its the most expensive. Are the other ones that are cheaper less quality or is it just mostly marketing.
