You are probably going to need one that has a replaceable rubber seal. Mirro pressure canners have been around for a long time now, and that is the only brand I have used. You can get a 22-quart one for around $65 at Walmart right now. Make sure that whatever you get has readily available replacement parts and maybe get a few extra of those replacement parts when you buy the pressure canner.
Alternatively, start looking for them thrift shops and garage sales or Craigslist and be prepared to get the replacement parts like the rubber seal or a lost pressure gauge (weight type rather than a dial = fewer moving parts).
I hope some other people have some suggestions, too, because I don’t know about any other brands. Presto is another common brand.
