I put the PBR ceramic pads on my 1997 E420. They cost about $40 and did squeal a tiny bit so i took them off and put the quite goo on the back of them. They stop very very well in the wet and the dry and produce very little dust.

Dallas is flat and traffic is pretty decent in Dallas so brakes don't get so much of a work out as they did when i lived in Atlanta. I suspect that these pads will last a while but I'll report back in a year or so.
