I need a heavy duty stand mixer with a minimum of 6 quart capacity that will do anything from whip egg whites to knead dense grained bread. I'm leaning toward the KA Professional 600 or the Bosch Universal. I looked at posts on Chowhound and it appears the most recent postings in that discussion were in 2006 or so. DeLonghi got raves but it appears DeLonghi no longer makes stand mixers (and other things change in 7 years as well.) Does anyone who frequently uses a mixer for a variety of uses have a strong opinion about their mixer. Oh, of course I investigated Hobart. Only 3 speeds but primarily a price tag of over $2200 for a 6 quart takes it way out of the scope of what I want and need a mixer for.
