I've prepared big ones and little ones, boars and sows. I kill and butcher my own just like I do any other game animal. It takes time but it is all part of the total experience that hunting represents. I am not a sausage maker, so I have little experience there, but I can truly say and I often have, that the feral hogs I've killed and butchered represent a cross between venison and pork to my taste buds. You get the sweetness of the pork and the woodyness(acorn taste) of the venison. For ease of handling, I would stick with pigs in the 50 to 150 pound range. Kill them with a well placed shot(normally low, behind the shoulder), gut and cool them ASAP, just like you should any other animal, and butcher to your satisfaction. I remove excess fat, but will leave some for flavor and moistness. I've killed some hogs that had an inch or two of fat something you seldom find on Texas whitetails. I make roast out of the shoulders and hams, and steaks out of the loin. I've cooked them on the smoker, in the oven, on the grill and in the crock pot. Slow, moist cooking is the best, which is also true with most game animals. I've got a whole 60 pounder in the freezer right now that I need to smoke for my friends. Because of this post, I feel a pig picken coming on. Try it, you'll like it.
