In my non-expert opinion, any aftermarket pulley you get that I know of will have different weight (more or less) than the 9lbs factory pulley. I've ridden Harleys for years and that's the most unbalanced engine I know of and it keeps on running. I put a harmonic balancer in mine to smooth it out to save my hands and butt from falling asleep but not to make the crankshaft or pistons last longer.

I think the looks a purely psychological, no one likes to pay a lot of money for a piece of ugly metal to put on thier beautiful MB! It should show the care in design and manufacturing befitting a fine car such as ours.
Again, what about balance concerns with the pulley. Aren't the crank pulleys harmonically balanced on the stock unit? If so, won't a new pulley upset the balance? On all the engines I've built when the crank/pulley/rods/pistons came back from balancing the pulley usually had some material taken off to balance the system. Does MB do this? Kleemann...Buellwinkle...anyone...?

Certain manufacturing methods provide more consistant results than others- MBZ parts do not vary in the same way as say a Chevy 350. As Lynn mentioned as long as the parts are within spec- it goes together.
The "damper" is a dead mass on the crank pulley through which no belt force is transmitted- it is "tuned" to a freq. This freq happens twice in the rev range of an I4 engine. The sole purpose of this damper is to reduce the vibrations of the engine at these two points. Are these forces enough to break the crank is the damper is removed?- no. Its a question of building an inherently bumpy engine in a way that attempts to smooth it out. You cannot tell any difference with the stock pulley or alloy one- I think even Buellwinkle will back me up on this one.

I can't tell the difference from idle to redline on my car with the ASP pulley vs. stock in noise or vibrations other than additional S/C whine during hard accelleration. This also applies to an SLK230 I drove with a Kleemann alloy pulley, before and after.
I would think that if the pulley caused a heavy object like the crankshaft to vibrate or shake I would notice it.
