I was wondering the diffrence is on all the pulleys being sold at the supporting vendors sites. I looked at them and just about all say they are metco. I looked at metco's site and could not find any prices on them...my question is this. I want to buy a 6# pulley and I do not need a quick change or any of that I just want to know why the varied prices and who has the cheapest with a belt. I have looked and looked and I cannot get a handle on all, if any diffrences between them.
