20# mixers? What's on sale? What's good?

[sidpost]

I thought I saw where the meat mixers were going on sale but, checking the past couple of days I haven’t seen anything. The 13 days of Christmas suggested yesterday was the day for the 20# mixer sale but, nothing.

So, I have the grinder and stuffer but, I want to add a 20# mixer. What are the main differences in function, quality, and, costs?

Thanks!
