That link is what I used. You can use your oven, but you have to keep it on it's lowest setting (150 degrees F) and open so you don't actually cook the meat. You just want to dry it out. Cuts of meat need to have as little fat on them as possible - Fat goes rancid and you don't want that, even after it dries. The less fat there is, the longer it will keep.
As for flavor, I didn't follow the recipe in the link. I just picked up some BBQ sauce and through the strips of meat into a bag with the sauce and put it in the fridge for 24 hours.
Total cost to make 2 lbs. of Jerky - roughly $7~8. That's fairly cheap compared to the $5~7 bags you can buy that typically only have 5 or six strips. In the picture above, that's about 1 lb of beef.
Around these parts it's even more expensive, and not worth the money for what you get at all. I'm dying to make my own but I think I'm going to go with just salt and black peppercorns and see how it comes out... Thanks for the info!
