If being hand-cranked is a turn off for a grinder, you can get capable home-use only electric grinders from bass-pro, gander mountain, cabela's, northern tool, grizzly industrial for less than $100.00, they are not commercial units, that is why the low price, but with low price comes low quality too.
To get into a commercial table-top unit, or a Hobart grinder head, your going to be spending quite a bit more.
I got my #22 commercial power unit and grinder head off craigslist for a little over $200.00, the retail cost for the model I got was in excess of $600.00
I have used the Hobart shredder attachments for many things, they work great. But I just prefer a ground cheese over shredded, and I prefer sliced over either ground or shredded.
