Brake rotor Quality question

[yaofeng]

I have a set of no name front rotors from fleabay on my 525 for the last 10k miles.

Has anyone ever purchased brake rotors on ebay? I did a search and came upon sellers with perfect feedback that seem to sell a lot of rotors the worry is about quality. How can an auction be for 4 rotors for a 1990 535I and be only $79 plus shipping? I'm still waiting on the shipping quote but that is dirt cheap.

I'm off to look at Struts next.
