So, I bought my wife a Kitchenaide mixer for xmas from a local high end cooking boutique. Just saw what looks to my untrained eye the same thing (with far fewer color choices) at Costco for signficantly less. Is there a difference in performance/reliability etc?
I know with tvs the Costco model is not the same as what one gets from a true electronics store. I know nothing about Kitchen appliances.

Thanks.
