to make pie and cookie, i guess you'd better own one mixer which get the function of slow start, by this way the flour will not scatter out.
and, if making pies and coolies is really your favorite, you want to do it every often, it's a good idea to get one standing mixer with timer. by this way you can do something others while the mixer is working. you don't have to stand there to wait.
i own one Cuisinart Stand Mixers, the model is SM-55 5-1/2-Quart, you can visit my hub to know more of my experience.
