@bregent : I definitely did look into that attachment, but ultimately decided against it. The reason is a lot of multipurpose tools I seen do different jobs poorly and the consumer is better off in the end by going with a dedicated tool designed specifically for the task at hand.
In this case, I checked Chowhound and other food forums and the general consensus is the KA grinder attachment is very slow and no match for a dedicated grinder. It also emits some type of grey ooze which is enough cause for concern to keep me away.
Nevertheless, I will openly admit that it's overkill and despite the above consensus, many readers still suggested the KA attachment for my particular situation because it's cheaper. I don't think that matters though, because it's a gift to my niece and one that I hope she is able to use for many years. Getting her one of the best grinders and stuffers on the market hopefully will enable her to enjoy this experience so much that she will become an instant fan and cook me all sorts of goodies all the time! I always have my fingers crossed that this is end result!
