Do any of use steam canners? My grandmother just purchased one recently and she loves it. I've read some positive and negative things about them, but the negatives seem to be just because the government won't approve of them because they haven't really tested them. I am looking to get into canning. I have canned deer meat before, so I am not a complete noob, but I was wondering what your experiences are with steam canners. Would you go steam canner or traditional water bath? I will be buying a pressure canner as well for deer meat. Are the Presto pressure canners at Wal Mart good ones?
