Best Pressure canners to buy.

I review my pressure canners and why I bought them

I have 2 presto 16 1 presto 23. They range in age from 50 to 5 years. All work perfectly.
I have 3 AAs. I like them but they are a pain on the ass to get the lid on even. If the lid is not even it will leak steam like crazy.

How long does the tank of propane last? I’d be afraid run out while processing?

I want to start canning, but i physically can't do the stovetop pots, but that electric one has my interest.
