First Strike Rations seem to be hard to find, I've seen them on Ebay for about $40.00 with additional shipping costs. Here is a link to a recent auction:

Just as an exercise I decided to try and make a home made FSR. The idea was to have a meal with a reasonably long shelf life without refrigeration and to keep the cost under $20.00 without using heavily preserved items. With a few changes and substituting cheaper jerky for the Tanka bar the cost could probably be lowered to about $10 - $12. I already had the Bridgeford sandwiches and after a quick trip to a supermarket and a natural food store this is what I came up with.
