for a grinder, depends on how much you are doing. I've had one of those little grinders and it sucked. I was also doing 100 pounds at a time.
If you are doing only a few pounds, consider the kitchen-aid blender with attachments. More versital tool. I have one and it does great if you are making a small amount of sausage or something. Works good for larger amounts, just slow.
I also have a cheaper slicer. It sucks to. Pretty much unusable.
bottom line, you get what you pay for.
