I think one good strategy is to buy the highest volume product -- the more of a widget someone makes, the better they are at it.

For example, a Ford Focus or Chevy Malibu is a lot more reliable and cheaper to maintain than a fancier and more fun car. Loads of third party parts, etc.

Regarding the mixer, I understand they changed the gears to plastic so they would strip without damaging the motor. Easier to replace a cheap set of seats than an expensive motor.
