I've been trying for weeks to come up with some novel peice of news that I could rif off of to use this link I found. But I simply can't find one.
So if you find freeze-dried foods too expensive for your prepping budget, you might want to talk to a few friends and go in together on a personal freeze drying machine. Yep, it's pricey, but split 4 ways it will set you back the price of a nice AR. And able to dry 2 #10 cans per 24 hour batch, this thing would allow 4 families to put back some serious food in a hurry.
Something to consider once you're squared away in most of the basic areas.
