Head Bolt Replacement - Advice - Who has had this done?

Has anyone had this work performed either by an indy or Benz dealer? Ball park pricing through an Indy?
Thanks for any feedback.
I don't think it is as big a problem as the internet made it out to be, the number of cars that had actual failures is fairly low...I've had my M156 for 5 years with zero issues. I too was worried prior to purchase, but all that sleep was lost for nuttin'.
