I've had a Bosch for about 9 years. It's trouble free and as slick and clean on the inside today as was when I bought it. FYI, Kenmore, AKA Sears, is manufactured by "name brand" companies such as GE and Whirlpool. They are usually of about the same quality as the name brand that makes them. These brands will change periodically, so check to see who made it. Kitchen Aid is, by all I've heard and excellent machine. I'd look first at the overall quality of the machine and the price second. They're all expensive, so go for quality.
