Looks good, just bought it, thanks all for the tip
Fi the max option is worth the extra money (gulp, it is quite a bit more) to me 'cos I do most of my editing on 16bit tiffs. It says it reads raw files as well. If you don't have this function then you can only work on 8bit jpegs/tiff, which is asking for deterioration in quality at the end of the exercise. So my advice is go for the max one
