Upgrading my meat grinder

[scmoose]

Going to update to a better meat grinder, my 10 year old harbor freight grinder has far exceeded it life expectancy. Thinking of going with the Cabelas brand Carnivore line, I believe I can add a cuber to it. Should I spend the extra 50.00 and go with the 3/4 hp vs the 1/2 hp? Anyone use the Carnivore line of grinders? I may process 3-4 deer a year.
