I am having trouble finding both rye and ww flour of a sufficiently fine mill. I'm considering buying a mill for this purpose. Does anyone know if the KitchenAid attachment is sufficient? The information on their web-site is a bit vague on this point. For stand alone mills, how much do they tend to weigh and what sort of price are they? I am having no luck finding one for domestic use in Australia and may need to order from the States.
