ebay rotors?

I have seen them and thought about them but there are things to consider, and reason why they are so cheap. The rotors sold on ebay are simply drilled though, but on a true drilled rotor you will have all of the drilled holes have a cylindrical "sleeve" to them so it will not comprimise the strength, the ebay rotors do not have this, that causes the rotors to just become weaker and more likely to fail, crack, or just plain suck. And since you probably aren't only using your car for extreme auto-X the use of such rotors are pretty much worthless, all they will do is cause you to go through your brake pads faster, kinda like a cheese grater for your brake pads.
