We can a lot at my house, but just water bath for high acid/acidifed foods and jams. I think last year we did 60 qts of tomatoes and it wasn't enough, so probably do 80 this year.
Haven't gotten into pressure canning, although for wort it seems great. For food, I'd rather freeze stuff that needs pressure canned. Bought a large deep freeze when we got married.
Never gotten on any forums on the subject, but there are a lot of good books about canning.
