i have a kitchen aid and LOVE It. Actually the one I own, is the one my parents got when they were married 38 years ago. My mom wanted a bigger one, so she bought the bigger model and I got the old one. It still runs just as good as a new one.
You only get the whisk, bread hook, and the paddle, everything else you buy extra, and you don't need to buy them at all. I would recommend the one where the bowl goes up and down. my sister had the one where it screws in, and hated it, she finally gave that away and bought with it going up and down. I feel that it's more secure in there.
