I did a lot of research on mills - it really came down to the controversy between Monster Mill and Crankensteins (do a forum search if interested) and I determined that I didn't want to take my business to either company as the bad blood turned me off (my personal opinion) so I went with a neutral party, Rebel Brewer and their Rebel Mill. No forum wars or controversy or bad blood spewed out on these forums being associated with that mill and I respect that.
