Sasa - have a look at this link - it gives you actual details about quantities of dough..
Magimix

It's not for a big batch of dough - although can handle quite a lot of liquid, cake mixes etc and is really strong..

I have a Kenwood for cakes and dough - I have the big mother (the professional chef)..and it's excellent. When I do a smaller batch - love the Magimix..

Honestly, I think it's the best one available..and I do my homework.

Be interested in what you end up deciding on..
