If you do not need to scan large format, the Nikon 8000-9000 are hard to beat. I have the 9000 and get grain sharp scans from medium format tmax 100 film. I do use the glass carrier, it is a pain to keep clean, but if you put in the time, you will get great results. I use the Nikonscan software and usually do minimal modifications prior to more extensive work in Photoshop. While I think good MF results can be obtained from a flatbed, I have tested my Microtek 1800f (usually used for 4x5), I think you'll get less than stellar results with 35mm.
Good luck.
