Buckwheat HELP

I 'm growing a patch of buckwheat this year for the first time. I just found out that it needs to be dehulled. But all I've been able to find are home mills that grind seeds into flour. I don't want that. All I want to do is remove the hulls and be left with the groats, which I can then toast and make into kasha.

Can anyone recommend a mill that will do this? The only one I have heard about is Country Living Mills, but the sticker price on it is out of my price range (nearly $800).

I had this problem with rice.  I had a mill with steel grinding plates which I removed and made ones with black walnut wood.   Adjusted the spacing on the plates until they split the hulls but not the grain.
