If you do get a Kitchen Aid, I recommend the kind where the bowl drops down, and not the kind where the head rotates upward (which is the kind I have). The kind I have makes it too hard to get into the bowl. Costco usually has a pretty good price on the kind where the bowl drops down.
I think the versions where the bowl drops down are a little higher power, too, which is good.
As for shows using Kitchen Aid, I wouldn't put too much "stock" (pardon the pun) into those. KA probably pays them to use their product.
