I'm interested in purchasing a sausage maker or some sort of meat grinder/sausage filler combo. I do not want anything professional-grade or for very large volumes, just something relatively easy to use (and, perhaps more importantly, easy to clean) and that performs well.
For relatively small quantities (<10 pounds), the meat grinder / sausage stuffer attachment for a KitchenAid mixer does a good job. Of course, you need a KitchenAid mixer...
Alan and Calamity are right - the Kitchen Aid is great for intermediate jobs. The KA has a meat grinder attachment, but you then have to get the separate sausage stuffer kit - there is also a wide tray kit that helps. Here's a source for all that:
Here's a source for a number of more robust units (as well as all kinds of sausage making goodies):
I've had my Kitchen Aid since 1975 & have ground & stuffed hundreds of lbs. of sausage with it - in batches of up to 25 lbs. And it's been used for dozens of loaves of bread.
It's a wonderful piece of machinery. I don't know if the new ones will hold up like this one. In the 34 years I've had it I've only had to replace one seal. It's a true workhorse.
I have a Porkert brand hand grinder that works very well. It is made in the Czech republic and is tinned steel. The blade and some other parts are raw steel so you need to always wash and dry it well right away (not that you'll be letting raw meat sit around anyway!). They have several different sizes with numbers that I don't quite understand, but 5 is small, 8 is medium, and large is 10 and up (I've seen 32's which bolt to a table. The smaller ones have a regular clamp.)
I have an 8 and it is quite easy to grind 4 or 5 pounds of meat. It also comes with stuffing funnels so that you can make sausages easily.
This one was highly recommended on a sausage site a while ago (can't remember which one) and it was a great purchase. I'd been using a really old "Universal Food Chopper" (the thing was probably from 1905) and it was a pain.
They go for around $50 or so new. I got mine on eBay for about 18 shipped, but I was lucky. If you're willing to risk eBay they are pretty common and around $25-30ish.
