I bought my Kitchen Aid Mixer 34 years ago and it still hums right along.
I bought the shield that sits atop the bowl and helps with the flour puffing back at you but didn't use that after a few years, small kitchen something had to go and I chose that. Don't regret it, didn't need it.
Mom used her sausage stuffer and meat grinder, I'm not into that but she enjoyed them. If you don't own a food processor the veggie slicer/grater might be nice, Now you will need to make a cover for it., Lots of free patterns online.
