I have heard many mixed views on drilled rotors with some saying they are good, and some saying they are not. Personally, I did not really notice much of a difference after I installed mine.
If you do want drilled rotors though, I would go for something better. Brakes are not something you should go cheap on.
I got the summit brand rotors that some people have recommended here. A lot of people on this forum use the R1 rotors. Personally, I like the summit rotors more because of their curved vanes rather than the straight R1 rotor vanes.
Ion also mentioned these in another thread about rotors. They seem ok.

Like mentioned here, and a couple times before in this forum though, do not go the cheap route with brakes.
