I've been searching for an optical film duplicator which will accept both 35mm and medium format up to 6x9.

Pentax announced a film duplicator meeting my requirements in 2014 but I've been unable to find any substantial reviews of it on the web or elsewhere.

Has anybody used it and, if so, what is your opinion? Its pretty pricey so I don't want to splash out if it doesn't work well but I do have a lot of old negatives I want to copy.
