In the UK many Pro labs are using minilab equipment, and have been for quite a few years now, for 35mm & 120 films. The two main labs I used both ran Noritsu machines for neg processing and digital minilab printers, negative quality was excellent and no different to when they used dunk dip machines.

The quality comes from the labs attention to detail, the training & experience of the staff. HAving been involved selling equipment (silver recovery) to minilabs I can honestly say that certain UK chains pay far more attention to training and quality etc than others.
