On the subject of cross drilled rotors...
You'll want to be certain that the holes were drilled prior to the rotors being heat treated to minimize the occurrence of stress cracks beginning at the holes.
Brembo brand rotors that are sold by Brembo have this done correctly. Please be warned that other companies have purchased undrilled Brembo rotors and have drilled the holes themselves with little regard to proper placement.
While drilled rotors certainly look good on a car, radially milled grooves are probably a better choice on a car driven primarily on the street (i.,e., one that doesn't get new rotors every race weekend).
Whatever rotor you decide upon, you might want to consider having them cryogenically treated prior to use (used rotors can also be treated). I'm about to ship a set of stock M Rdstr/Coupe front rotors to be done by "300 Below"
