I have this one from Pensey's and WOULD NOT buy it again....
It works fine. However, it's a bit of a pain to unscrew the top which has a tiny spring it it. Heaven forbid I ever lose that spring because that would be the end of the mill's versitility.
Also...it takes two hands to use.
(edited to remove link. The grinder I have I bought from Penzey's years ago but it has a crank handle. I didn't realize it wasn't the same one until I was cooking tonight.)
