Vernon - In fact, I'm looking into that right now.  The web site says you need the KitchenAid with 325 watts.  I don't have that one, I have the one with 250 watts.  I'd be interested in a link to a review if you can find one.  I do not have any intention of making flour or anything like that.  I will just be doing small quantities of spices.  If I don't think the KitchenAid attachment will work, I'll buy the hand crank model with the mill grinder.  Both are around $90 so it doesn't really matter other than I wouldn't want to buy the KitchenAid one and find out my unit won't even grind some black pepper.
