I don't poke my snout in here often, but just wanted to say that canning meat is no different than water bath canning, the processing time takes longer.
5 years ago, I had around 3 dozen jars, and a water bath canner. Now, I have close to 3000 jars, 4 or 5 water bath canners, and I think 6 pressure canners. We also have 5 steam juicers. Al of this has been picked up from yard sales, or off of various classified ads, for pennies on the dollar. We don't need that many of each item, but we do loan the extras to those that are just learning. We keep track of who has how many jars, and what equipment. No, I don't want to sell it, but I will loan it to you, if I trust you.
More than one canner, of any type speeds the process up. Especially when pressure canning, with the long processing times. A water bath, you can dump the water, and start again. Pressure canners have to let the pressure drop naturally.
Pressure canning was something that I just had to jump into. My MIL was a source of info, but she told me I just had to do it, or I wouldn't learn.... She was right.
The older Ball Blue Books are the best! I picked up the newest edition, and gave it to the neighbor.
Follow the book, keep things clean, and sanitary, and you will never look back! the savings are huge! For meats, I would recommend a wide mouth jar though, same with beans. Canning our own dry beans has been a great thing.
Canning with your "other half" can also be a great way to spend time together, sharing in the work. Many of our "canning dates" have lasted until 3 or 4 in the morning, on a work day.
One other note to add.... All American canners are the bomb, but any pressure canner is better than no pressure canner.... Get what you can afford, and then save for the expensive one! That is the best advice I have, and I own all types.
