I've been happy thus far with the Power Stop Z36 rotor/pad kit. Amazon had a sale which made the Z36 cheaper than the Z23 kit at the time. Also did the power stop parking brake at the same time. Had an issue with fitment of the parking brake shoes (I initially tried using the parking shoes with the stock rotors, and decided to parts cannon the whole thing with new rotors/pads), and they sent out a new set no questions asked, and provided a return label to ship the old ones back. I'll definitely use Power Stop in the future.
