Wow 16ozs. thats alot of beet juice.Drinking that much fresh beet juice may be a bit ruff on your system.Juicing does the human body much good but does take some work.I own a greenstar2000 and do the majority of my juicing with the dual gear juicer.The greenstar is heavy duty and gives a great yield along with a high quality juice nutrient wise.I also own a breville which I use when the apples are in season.The breville elite is super fast and easy to clean and use.If your upper body strength is good then the mastication juicers are great.If not then centrifigal is the way to go.Good luck and happy juicing.
