Oldchenowth, The style and size of the chain changes the price of the chain. They have so many differant chain styles, cuts, and even carbide chains. But I run the cheapest base line chain they have and most of the time its always a green lable chain (the safe chains). Because I never know how is gonna use my saw. But I have no complaints about them. I have used all the other kinds and I cant see paying more for somthing that does the same thing with less safety. But I have people say they have to have that speceal chain. Each to there own I guess!
