from my experience, the OEM setup (rotor n pad) is the best. (the performace and the life of both)
my repair shop told me that OEM rotor can not be re-sufaced like others, usually the rotor will last 2 pads average.
you can try the aftermarket pads (EBC Greenstuff) which produce less break dust than the OEM but compensate higher wear rate than OEM.
I heard power slot (slotted) rotor is good if you don't want OEM setup!

I agree with Super that OEM is still the best way to go. I know of people warping their stock rotors with EBC pads. I had Porterfields with brand new rotors for a few months, and yes there was less dust, but they start squeeking A LOT (even though I put the grease on the back of the pad). Also, the brake pedal felt REALLY soft. I switched back to OEM about a couple weeks ago. Sure, it gets pretty dusty, but the brake feel is MUCH better.
If you want rotors that look nicer, slotted would be better than most cross drilled...cross drilled tend to crack pretty easily. If you get cross drilled, make sure it has the cadmium coating so it doesn't rust as quickly, and if possible, have them frozen first (some companies offer this service...check out www.myroadster.net).
I hear Axxis Metal Masters are good pads that are low dust...
If you want better braking though, look into bigger brake kits (or get brakes from some C36/C43, etc).

pgauto.com sells brand new OEM front rotor for W202 at $35.38/each.
matt:
i have a question, does it matter to install either left or right side? pgauto.com does not specific the right or left rotor.

No. A front rotor is a front rotor. Simply flip it the other way. This may or may not be true for specialized rotors that are drilled, etc.
The obvious difference between rear and front rotors are the dimensions. But left or right, no difference for normal rotors.
If you are going to do this yourself, it's a prime opportunity to re-pack your bearings.

what is re-pack the bearing? sorry to ask you this, but I am new in this field. i used to have the dealer take care of the car for me. but now i think i need to know what actually they are doing to my car.
I have replaced wheel bearing of my Porsche before, is it the same thing? (lots of small metal ***** packed together to make the wheel/axel turn smoothly)?
thanks!

Exactly the same thing as on the Porsche. I usually do it simply because I have the wheel off and the hub is available, why not do it now versus later. Simply clean up the bearing, check for wear and then re-grease and put the back. I've always refered to it as 're-packing the bearings'. The wheel bearing sits in the hub, the hub on the spindle. Want to make sure it's a nice clean bearing system.
You'll probably want to optain a tool for tapping the seals out and then back in. I've always replaced the seals because after taking them out they can be pretty dinged up with the right tool.
