I bought a Cabela's variety pack that has 4 flavors in it that will do 5 pounds of meat per packet. Check out my pork jerky thread in how to make pork section. Just make sure you have at least 5# of meat or slightly more or it may be salty as the meat absorbs the wet mixture when in the fridge for 24 hours.
The MAK2 and Memphis worked really well at low temp in the smoke creation. I probably had a dozen people try the jerky, both beef and pork that I made, and all of them loved the smoke flavor and mentioned that it was not overwhelming.
The seasoning packets end up costing about $1 per pound of net jerky meat after cooking. They sell individual flavors to that are enough to make 15 or 20 pounds in packets to make 5 pounds at a time.
On Amazon, there are a few other brands of jerky seasoning too. The Cabela's was fine, but I am going to make my own when I am through with all that I bought.
www.jerkyholic.com has some recipes that I plan to try. I just got a container of the cure this week so I am ready to get started experimenting. I would start with the Cabela's or one of the other premixed seasonings first and make a batch or so. Once you go through the process and enjoy what you made, you should be comfortable enough to make your own using recipes online if you have the ingredients.
