> If i am scanning the negatives with a camera and light source and after inverting, a greenish mask is still present, as like in the first conversion example they give, a few tweaks of a few sliders in photo editing software is enough to correct it.

I think this is a major point. I applaud the effort of the post and would (as a Mamiya 7 shooter!) love a whole unit better than the Epson V600, but correcting a color cast in the film scan is trivially easy in an photo editing tools these days. I scan and get tifs and can tweak to whatever. More important are the iris/optics of the scanner itself and how flat the film is inside the bed.
