Ultramill Grain Mill recommended (?) for milling Field Corn
The only reason I am posting this link is because some home millers have expressed interest in milling field corn (aka "dent corn") into flour for cornbread. Serious cornbread bakers (I include myself among this group) often prefer a slightly gritty (coarse) flour for cornbread. Many of the electric grain mills on the market explicitly state they *cannot* mill corn meal or corn flour from field corn.
If you want to mill field corn into flour for corn bread this blurb from pleasanthillgrain.com on the Ultramill Grain Mill may be of interest
Great for Field Corn: Among high speed impact-style grain mills, the Ultramill is the outstanding choice for milling field corn to flour because its inlet handles corn kernels better than any other mill in this category.

I have *not* used this mill and have no idea if the claim is good.
