I am going to give EBC "Greenstuff" pads a try. Tire Rack sells them and I have heard they are pretty good. The most impressive thing I read about them was in a SCC article on a group of modified Acura RSX's. The car that just had these pads added had a huge difference in stopping distance over stock, and comparable to the other cars that had more radical brake work.
