Check with your local LDS (Mormon) church before investing a lot of money. Because of the directive that all Mormon families should have a years' worth of food on hand, many of them collectively own sophisticated canning/sealing hardware. The second tenet of Mormonism (pardon my blasphemy, not religious) seems to be "make a profit," (hey, there's a reason their symbol is a beehive) so they wisely rent out the time that their assets sit unused. When I lived in Boise (LDS population second only to SLC) I also found a large reservoir of food storage knowledge that they were willing to share. Of course there is proselytizing attached to it, but Mormons are self-sufficient, intelligent and hard-working people who recognize and respect the same values in others.
