Query: BUYER BEWARE

I purchased this mixer in May 2008. I used it 3-4 times a day, usually to whip cream or egg whites, occasionally cookie batters. It has not even been one year, and my mixer no longer shifts gears for different speeds. I essentially have a mixer with two speeds, low and high. I contacted kitchenaid and was basically told tough luck, your warranty expired. I expected kitchenaid to stand by their products, but apparently not. So now I'm stuck with a virtually useless stand mixer that I paid over $300 for.
