I'd actually trust one of the labs I've used for nearly 30 years, we have a more than good relationship as we used to do their B&W printing while they were getting established. The owner was once a Durst technician, he's 110% quality images, if he uses a non optical route then it's the best.

Here isn't the place to discuss this, personally I don't discuss digital aspect but it's a reality that we live with. I just use what gives good results.
