If you're doing batches up to 5 lbs. in hog casings (which are the larger size casings for italian, bratwurst, and so on), almost any grinder with a stuffing horn will work.
If you're doing more than 5 lbs. at a whack, or if you want to stuff sheep casings (which are the smaller size, breakfast links, hot dogs, and so on), you'll find using a grinder is quite a chore (to put it mildly).
I recently picked up a Dakotah TNT stuffer, which has a 10 lb. capacity and is water-powered. I can't offer any reviews or advice because I have yet to use it. I can say that it's the lowest-priced stuffer with a 10 lb. capacity that I've found out there.
Stuffer's supply company has a PDF file on their website with 100+ recipes for making sausage and other kinds of processed meat, which is a great starting point.
As far as equipment, casings, and other supplies: I buy all my gear from The Sausage Source (
www.sausagesource.com). Their whole catalog is on the website. You may find sources closer to you, but I have had nothing but great service from Rick, and he's not at all shy about giving advice and answering questions. He's got quite a passion for it, and all his customers benefit from that.
He also sells starter kits which consist of a grinder, stuffing tubes, hog casings, and several different varieties of pre-mixed sausage seasonings good for 2 lbs. each (just add ground pork and water, mix, stuff, cook, and eat). It's a great way to get started out!
As you can see from Dutch's recipe, most of what you really need for sausage you've probably already got in the spice rack. Everything else you might need is readily available online.
One word of advice: where you see a sausage recipe calling for salt, avoid iodized salt. It can leave an unpleasant aftertaste in some sausage. Kosher salt or pickling/canning salt are usually better choices.
I hope I'm making this less confusing instead of more confusing! :?
I would recommend checking those two sites out, and there's enough of us here doing it to fill in any details you need.
Good luck on the hunt!
