Your budget is high enough you might consider a commercial Hobart, or at least one that’s built with an interchangeable commercial attachment (#12) between power head and grinder. New Hobart is crazy expensive, but lightly used Hobart equipment has all parts available if needed and will out live us all. Hobart knock offs are everywhere and almost anything aimed at restaurants will have the #12 attachment point.
The same grinder attachment can be used with a simple power head or a big commercial mixer. If your family bakes a lot of bread, or makes a lot of pizza, a 12qt Hobart mixer weighs about 150 lbs and doesn’t break a sweat mixing twice the dough that would kill a kitchaid mixer. The mixer in the picture has the proportions of of a home mixer, but it’s much much larger. We have a different brand and it would be hard to go back to non commercial for big mixing and grinding.
The Hobart clone grinding attachment shown is typical and only runs about $350. Many lower quality stand alone grinders say they are commercial grade, but the meat tray has to have extra supports because the metal is thin, the blades and plates are thinner, the grinder and power head have a proprietary attachment, and overall are cheaply made.
A restaurant supply store can be a good place to put eye on something like this, but just searching for Hobart meat grinder will turn up a lot.
edit: First time I read the original post I missed that you’re looking for a bigger 220v grinder - these are only about 3/4 hp 115v. disregard
