Anybody using Ebay/chinese BB timing gear set?

I have dealt with China/Tiawan forged and machined products for many years. The theory of the dollar store holds through most of their products. It's cheap and it only costs a buck, so if it breaks it's only a buck. The way they can get their pricing so low is not only the labor. They subcontract to subcontractors that sub it to other subs who then sub it again. When you have a train of middle men, usually the quality is the only thing left to scrimp. For a street car that only has to show it's OK. But for race that $100-$500 that you save won't pay for the rebuild.
