I mulled this one over for a while, too. I ended up going with the 15-hole replica rims that Tirerack.com sells. Shops with experience doing these kinds of rims wanted roughly $70 each to powdercoat the originals. You have to pay to have the tires removed and then reinstalled. Not to mention leaving your car on jack stands for a week or two and having to deliver and pick up the rims.
I ordered the replicas for $99 each through Discount tire. Since I bought my tires from them, they didn't charge me to swap the rims. My total cost was $99 + tax + what tirerack charged them for shipping the rims UPS ground. New center caps and lug bolts are included although the lug bolts are shorter than the original so I didn't use them.
I had discount tire save the boxes for me and then sold my original rims for $200 plus shipping to someone on another Mercedes board. So my net cost was just over $200.
