I happen to really like the Magic Mill. It’s a workhorse, and it really does the job well. My only complaint is that it’s VERY heavy (which for me is an issue as I have an arthralgia-related condition which makes heavy lifting kind of painful), but as long as you are smarter than me and you don’t keep it in the cabinet under the sink it really shouldn’t be a big deal. It’s absolutely fantastic- I love the dough hook and that gizmo that scrapes the edges of the bowl. I also use it to make triple batches of cakes and cookies for yom tov.
I’ve never had a Bosch, so it might be way better than this for all I know, but the Magic Mill is nothing to sneeze at.
