What is your opinion on the foot control ? Is it needed or not ?
I don't have one but I'm in the camp of the not really super fhelpful for grinding bout would be helpful on an electric stuffer.
I prep all my meat first then grind OR I have a 2nd pair of hands helping me cut meat and grind. My meat is chilled to about 34F degrees so we can cut it.
My particular grinder does not heat up at all during this as the cold meat keeps the parts really cold as well.
Another personal thing, if I have to get another grinder I would look hard and research to find one that doesn't heat up like so many have problems with. Mine doesn't do any such kind of heating, but it is also not a super powerful one so maybe that's the key.
Coming full circle. You have to cut the meat anyhow so if you prep and do it before or have a 2nd pair of hands to cut and feed as you go, then I don't see a super useful need.
Do what you feel will make you happy though. That is what matters :)
