My wife wants a stand mixer for her birthday, and I have been reading up on the various models all evening.
Costco has a Costco only model (KG25H3XLS) for $279. It is a 5 qt model with a 475 watt motor. Nearest I can tell, the 6 qt Pro series 620 is around $350, and has a 575 watt motor.
My wife does lots of breads, muffins, cookies, etc. She likes to do large batches.
If anyone has any insight as to whether the 6xx series is worth the extra $75, I would love to hear it.
