$100 is beyond our means right now.I’d recommend stay away from the hand crank grinders. They normally suck. A $100 electric grinder from cabelas or academy will serve you well.
Not just used for venison either. Having a meat grinder opens up lots of culinary doors. Fresh ground chuck for burgers is the best! We often buy reduced meats from the grocery store then take it home, debone, grind/freeze. Also I often do tough chickens (like butchering a mature rooster) by just skinning instead of plucking, then deboned and ground up. Ground chicken is good in chilli, pasta sauce, seasoned for tacos, etc
