A:AnswerI bought mine in-store. It was the Professional 5 Plus--the one pictured instead of the one described. It is 525 Watts. As far as I can tell, it is a step up from the one described but for the same price as described (they didn't even have the model described in the store).

A:AnswerGo to the KitchenAid website. It will tell you all of the attachments and accessories that are available for a particular KitchenAid mixer model. You can even order the parts on-line and have them shipped to your house.
