Buy the Bosch. It is the VERY BEST machine to have. I have a Kenwood Major and the best machine ever is the Bosch to make challahs, kokosh, breads, bagels, and the cakes etc.
It is heavy duty and it will B’EH last for many long, good baking years, to do for many simachot I’YH.
Is the one you are think of purchasing a 1000 watt machine or a 850 watt machine? How old is the model? Does the machine come with a stainless steel bowl with a column in it like a angel pan or is the stainless steel bowl flat? I have two bowls. One with the column (like the angel pan), I use for all cakes, but not kokosh or fruit cakes. I have another bowl, a stainless steel bowl for the challahs, breads, bagel, kokosh, rugalach dough, cookie dough, heavy fruit cake mixture or any heavy doughs. If the machine does not have the full stainless steel bowl, it is worth buying one online and I will send the link to you, if you need it. My friend just purchased a Bosch and she is estatic with it. Her sister is now buying one. The Bosch has a plastic cover so the flour does not fly everywhere. The Mill does not have a cover and the flour goes everywherte, and goes at a smaller speed due to the wattage. You can also get an attachment for a shredder/slicer for the Bosch.
It is a phenominal machine worth every single penny!!!!
