Yeah that is similar to the one I have. Dehydrators are slow but that is what helps the beef get more tender and flavor infused. A dehydrator with a built in timer is absolute essential. The first 2 I had did not have a timer so I was in the same boat of spending 2 days to complete everything.
My routine is order from Publix, they will slice it for you, I usually get 5 lbs at a time. Pick up on the way home, mix whatever marinade I'm using for that batch then soak the meat in the marinade in 2 large rectangular Rubbermaid containers overnight. Throw on the dehydrator before I leave for the office and its done that afternoon. I usually do 150 degrees for 8 hrs.
