I don't use mine a whole lot, but I do like it. I got a steal of a deal on it...$129 for a 5 quart Commercial model.
Amazon (and the ShopKitchenAid.com website) sometimes has refurbs for sale, and you can get a good deal. For an example, see this one:

Don't be scared off by the word refurbished. Kitchen Aid policy is a bit different than most companies. Let's say that a person receives a Kitchen Aid mixer as a gift, doesn't want it, and returns it to the store. Regardless of whether the box has even been opened, Kitchen Aid requests that the store return the item to the factory. Once there, it's opened up, fully tested, and repackaged as a refurb unit. Of course, some of the units probably had legitimate problems too, but everything is checked out and fixed.
If you like to make bread dough in double batches, you might want to consider the 5 or 6-quart Professional model with all steel gears and a circuit breaker...it's considered the toughest model, although it is more expensive. FYI, some of the colors have a $50 rebate at Amazon right now, if you prefer to buy new instead of refurbed.
