I had a similar grinder to the Sam Baere. It held up for a couple of years just doing the occasional chuck or pork butt grind but eventually failed. I bit the bullet and bought the Cabelas 1/2hp commercial model. I can't throw meat in it fast enough..never slows down. If you can afford it, it's the way to go.
my 2 cents
GOSM smoker (gas)
Weber Gasser (2)
I'd rather have a bottle in front of me then a frontal lobotomy
