<<Disclaimer: Verify this information before applying it to your situation.>> Just wanted to let everybody know the concensus I got on the kitchen aid machine was that the more wattage the better. I called the manufacturer and they said it all depends on how much you would use one, they said the 250 watt would be perfectly servicable for someone who would use it once a week or so. Most people recommended at least the 300 watt. I think I am going to spring for the 350 as the price difference is not that great and its a one time investment. Janet in Maine
