I have a Kitchenaid 4.5 quart 250 watts model and love it. However, I've made a couple of batches of brioche and the motor hasn't been the same. Also, the bowl is a bit too small to make 2 loaves of bread. I've been eying a 6 quart model with more power.
I think the food processor is better machine for biscuits and pie doughs but since I make them very rarely, I can't justify the cost.
