I am currently using a Reflecta Pro Scan 7200 with a native resolution of 3600 dpi. The real resolution of the scamner as tested by filmscannerinfo is not too far off. I honestly am getting much better scans than with my previous Nikon L5000, perhaps not in resolution, which is quite similar, but in terms of color reproduction and accuracy. Eventhough Plustek scanners are generally producing much lower resolution than advertised, usually just about half, however, I do believe this new generation of cheaply built and priced scanners is better or at least equal to the better built previous generation from Nikon and Minolta.
