i have bought parts from them also!
i saw those on e bay last week myself, lots of them, from early 16 models up thru 20 series (if i remember correctly).
they want $250.00 for each one, a bit steep i feel. i have never paid more than 100 for any of mine, except the kdss-17a stainless tub model i got from boston.
they say they are refurbished but i wonder what that means. i have found kitchenaids to have rusty sumps when i get them and i always have to sand, prime, and paint that area as well as completely tear down the pump and motor to check everything before i consider any of mine as "restored".
to each his own but i would be a bit wary of what i was purchasing for that much money! i would at least want to know exactly what was done to the machine!
but for anyone out there that wants a kitchenaid, there they are!
