If you can't get to the Pioneer Meat Market in Ortonville, Minnesota, where they have the best jerky I've ever eaten, try King B. They have quite a good selection. From a dogpile search:

On edit: here is a recipe:
Jerky.
Meat doesn't have to be that expensive stuff. I like sirloin tip steak. Trim all fat out of 2 to 3 pounds and cut into strips about a quarter inch thick by one inch wide. (If you cut across the grain of the beef, it will be easier to tear and chew.)
Mix 2/3 cup soy sauce, 2/3 cup of worcestershire sauce, 1 teaspoon garlic powder, 1 teaspoon onion powder, 2 teaspoons of seasoning salt, such as Lawrey's. Toss in some liquid smoke if you feel like it.
Marinade the beef strips in this 10 -12 hours, or overnight. A plastic zip bag works great.
Drain meat on paper towels. I sprinkle them with a course black pepper at this point but you may not like that.
Insert a toothpick in the end of each strip, and hang on the grates of your oven rack, suspending them about midway in the oven. Line under the strips with aluminum foil, because they drip and it saves a lot of cleanup. Set oven at lowest temperature, put a wooden spoon in the edge of the door to hold it open a bit, allowing steam to escape. Smaller pieces may be dry in 2 and a half hours. Larger ones may take 4-5. As one recipe states, "you'll know when the meat is ready as your family will begin stealing jerky right out of the oven."
