Corona grain mill? Should i?

Hey,
I've read a couple threads and read these work fine. It's only $30. I figured I might get kne if no one objects. Is this a legit grain mill?

Also~ if you do have one, did you make any modifications to make it hold more grains? Show me done pics please.

They work fine. I have one. You'll need to do some small modifications to it (like adding a bucket to collect the grain, maybe adding a drill or electric motor to drive it. Hand cranking any mill gets old, fast). Malt/grain conditioning (see Braukaiser's wiki) is highly recommended for this type of mill.

I get efficiencies in the 80s with mine. Look for the "ugly junk" thread on here for the best pictures/instructions.

Ahhh very nice. Thank you

I went with the double bucket set-up and an allen-head bolt for my drill with a bit holder to hook to. My efficiency is nearly always in the mid-80's
