I suspect probably only a few of the major LDS home storage centers still have can sealers but it never hurts to ask around.
One of our group (prepper radio net) members is a morman, he's the one told us about our local LDS home storage center. Apparently, in the old days you went in and canned food on their machine.
We tried to do a group buy on a freeze dryer but everyone dragged their feet until one of the guys just bought one for himself. We pay him to use it but it's going to take two or three years for him to break even. A can sealer is about 1/3 the cost of a freeze dryer so the break even point would be much faster.
I would love a freeze dryer but I know that's not going to happen, to much $$ But a canner is more possible. I just retired this week so the pay cut makes things tough.. I think going in on one with another family of two is the best way ahead..
I will also try the LDSC, I have bought canned goods ect from them in the past.
