Check out post #12 in his thread. It tells you what canning supplies and equipment I use. I don't have prices though.

I can a lot of chicken broth. We use a lot but I also supply three other people. There are all kinds of uses for it and practically everything that goes in it is from the garden.
I can a lot of dill and sweet pickles, corn, green beans, beets, tomatoes, spaghetti sauce, and saurkraut. Our normal Saturday supper is a quart of vegetable soup I canned with cheese and crackers. Simple quick and good.
I can dried beans for the convenience. Any time you want beans just open a pint. They are already cooked so all you have to do is rinse them and heat them up. That's a lot better than having to cook them all day.
My Christmas gifts for certain people I actually like is about a dozen jars of various jams, jelly, and chutney made from fruits and berries I grow. Last year I included a quart of canned apple pie filling. Just heat up the crust and pour it in. I already have mint jelly canned and waiting for this Christmas.
Yes, I think canning is worthwhile.
