nissan altima, OEM pads are probably the only pads that won't squeal. Every aftermarket pad I've worked with has squealed, even after cutting the rotor, and cleaning everything. As for mileage on pads, depends on where you drive, and how you drive.
amr005, you do bring up a point of cross drilled rotors not being able to being turned, also remember that they should in theory given they are quality rotors should be fine w/o turning them. Heat is disipated quickly, but can overheat in certain hard braking situations, and crack. However a benefit is that everytime on the brakes your brake pad gets "swept" and doesn't create a hotspot which will warp your rotors, and thats the main reason that rotors are turned.
