I got an All-American canner several years ago. It’s a good, solid canner. But, I had trouble keeping the pressure steady. I think that had a lot to do with my stove rather than the canner. Jackie Clay recommends the All-American, and she cans enough every year she could supply her own grocery store if she wanted to!
More recently I bought a Presto digital pressure canner. That thing has been a Godsend! No more constant fiddling to keep the pressure steady, it monitors itself. Just plug it in and follow the directions on the screen. I did more canning with that thing in the first few months than I did the 10 years prior.
The only downside to the digital canner is that it requires a reliable source of electricity. The All-American just requires a heat source. If you’re in a situation where wood or propane are more available than electricity, you’ll probably do better with the All-American.
If you have the funds available, hedge your bets and get both, so you can use the digital for normal times and the non-digital during outages. But if you can only get one or the other, choose based on your own situation.
I have never had trouble keeping the temperature and pressure steady with mine.
I also like the weighted thing that jiggles when you are canning. You can listen for the jiggle from the other room and not worry about having to baby sit the batch.
