I started making some venison jerky and it comes out perfect (well at least the way I like it; not brittle but not soft either). I bought the Open Country 500watt dehydrator kit which came with the jerky gun, some spices/cure kits and the unit for like $60 at Gander Mountain (Caught it on sale).
Then I bought some Hi-Mountain spice/cure kits, all i use is ground meat. I can only dehydrate about 3 pounds of meat at a time (4 trays), but man the stuff is awesome! I mix the meat and the spices in a bowl with some water and let it marinate overnight in the fridge. Then I get up the next morning and load the jerky gun and load the trays. I let it dehydrate for 6 hours, (alternating the trays every 2 hours; even though with this unit you don't have to but I do anyway) and wipe off the excess grease and voila! Bon Apetite!
I am going to buy more trays so I can dehydrate more as between me and the family, the jerky don't last long!
