I have a 26 yr old Kitchen Aid I seldom use unless I am baking one cake. For bread I have a "Santos" kneading machine with a 11 qrt bowl (semi commercial).
Not lobe ago I was just looking at the Bosch website and they had a nice one with a 6 qrt bowl plus a blender attachment and it was on special. If you bought withing a certain number of days you also got a free Grain grinder (seoerate item that retails for almost $200.00). The whole thing was on special for under $400.00.
Go over o the forum "Recipes", there are a lot of bakers there. From what I have seen here over the last few years is that those who have a BIsch would not trade it for a KA or any other mixer.
Also try to Google:" Bosch mixers" and go to the manufacturer's website. You can look at all their models and pssiboly run into another special.
Kitchen Aid is no longer made by Hoibart, they sold the KA division years ago and the new mixers are no longer the same quality as they used to be.
