I use Akebonos on my minivans. Great stopping power, not too much dust. They are silent on a 3600 pound van...with brakes of a similar size to the e30. I think they were about $70 for the fronts. Definitely worth it.
I have EBC greens on the 318i with ATE's funky grooved rotors. I'd say they were far better than what was on the car, but I'm not sure those were OEM. They're not too dusty either, nearly silent. I bought them used, so they were already broken in. Not sure of price.
