Do you use Vitamix for grinding flour and kneading dough?

Hi,

I'm trying to decide between Vitamix super and regular. Super ones come with a dry cup, with which you can grind flour and knead dough. But I wonder if I would use it, and if it does a good job of grinding and kneading dough. Would you say it's worth it? I don't do much baking though. But if baking becomes a piece of cake with Vitamix, I might do more...

Thanks!
