I'll be honest, I don't think I need one but I would definitely like to have one. I absolutely love the look of a kitchen aid, I think it is a beautiful design object (on top of being a great tool and workhorse) that can last a very long time. That said, it is also very expensive and I have also heard that Kenwood is equally as good and often cheaper. I also like the look of the smeg one.
So which ones are the best and why? And what sort of style/model would I need? Realistically I would mainly use it for the occasional cake or muffins etc and to make dough for focaccia or flatbreads.
