Keep in mind, too, that that ATK review is for the KA Classic, which is a scaled-down (budget) version of the Artisan, so that'll be a slightly robust machine anyway.
SeriousEats did a similar review to that one, and they liked the Ambiano (sp?) mixer from ALDI. They said as long as it was working, it did a pretty good job for the home kitchen, but they didn't expect it to have the life expectancy of a KA.
My sis has a really crappy Hamilton-Beach or Sunbeam, one of those, and it's basically a hand mixer that fits in a stand and comes with a bowl. It even came with a dough hook. Can it knead bread? Not on your life.
My KA is still muscling through pizza doughs and bread doughs like a champ, 25+ years on, and doesn't show any signs of stopping any time soon, I like it very much, and it's frequently in use.
