Meat grinders?

What kind of meat grinders do you use for your raw meats? Anyone use the hand crank grinders? I just saw one selling on ebay and was wondering if they were any good. What do you recommend? I plan on grinding the bone with the meat.

All this research is making my brain hurt lol

Here's my meat grinder: http://devonrex.se/kokbok/images/redskap.jpg

It's important that all the details inside the grinder is made of metal, not plastic and that is h as an effect of at least 250W. Mine is 450W and it works like a charm. It only does bird though. Pork, beef and lamb bones are to hard.

I would never use a hand crank grinder.
