I have one too, and I like the 35mm setup because you can put two 6 frame strips into it, individually adjust the frames in prescan then set it to scan and it will do all six without needing any other help. It does pretty good for medium format but I had to make my own carrier for the film from mat board to get multiple frame scanning. With that I can do 3 frames at a time. I haven't shot any color 4x5 yet so I can't comment, but it does an excellent job with 35mm and medium format color.
