KitchenAid stand mixer meat grinder attachment

After several bad experiences lately, I am interested in grinding meat at home. Does anyone have experience in this practice? I have a KitchenAid stand mixer and after some research, I am interested in buying the meat grinder attachment. However, there are literally dozens of weird Chinese brands on Amazon purporting to sell an identical set for much less. AliExpress is even cheaper.

Has anyone bought and used the KitchenAid version? Has anyone tried a cheaper version?

Thank you for your advice.

Thank you to everybody who commented; I'm going to look for the official KitchenAid attachment at a good price.
