I have a presto 23 quart. I bought it because of the price and availability ($75 on sale at orchard supply). I bought it in August for albacore tuna season. i had never canned anything before.I canned almost 200 half pints of tuna, 24 half pints of venison, 24 half pints of sardines & herring. It was very simple and the finished product was amazing. I hate store bought canned tuna. I canned tuna with rosemary & garlic, lightly smoked , sriracha chili sauce & garlic and plain. It was a huge mistake sharing it with my friends and family. We only have about a dozen jars of plain tuna left. I think someone broke into my house and stole all of my chili garlic tuna.
My fishing buddies and I all got together to can a bunch of tuna. They had "all American" brand canners. We all agreed that my canner worked just as good for 1/4 of the price. The "all American" is a heavy duty canner that could take alot of abuse. The presto is great for the sportsman / gardener that would rather spend money on traps and ammo than kitchen stuff.
