Have any of you guys ever used the kitchenaid attachments such as the grinder and stuffer attachments. The wifey has a kitchenaid stand mixer and these seem like an economical way to get started. I am just starting and mot sure if it something I want to do so I won't be doing much anyway. I figure if I like a lot then I can buy some better equipment later, for now $50 seems like a pretty good way to get started and I am not out much if I don't like it. Thanks for your input in advance.
