If you find you need to replace it, I would highly recommend that Complete Book of Home Preserving. 400 recipes that cover more than I ever thought you could can and it is listed at $22.95
It has alot of helpful canning info in the back also. Altitude chart, produce purchasing guide, Problem solvers, ...
Lets hope not. However I got two books for that price on Amazon or E-bay. New ones too. I'm sure you can find the same deal for that one.
