You are talking about Spam, right? I grew up on that stuff, and it's good survival food, but for everyday or frequent eating I'll stick with the fresh. One of these days I'm going to learn how to make my own beef jerky. Since you eat ham and eggs often, you could probably buy fresh ham and use it up before it turns.

Chris has a very good point about the treatment of our meat. "Organic" or at least "all natural" meat is increasingly easier to find these days, and in popular opinion tastes oh so much better. The price can be daunting to buy organic food, though, so you should set some priorities in regards to your food budget.
