You basically have two choices - a Corona style mill ($30 - $50 range), or a roller mill made for brewing ($100 and on up). Many people rave about how great Corona mills are (after making adjustments) and say you don't need to spend the money on a roller mill. Many people make great beer with a Corona mill. You mentioned quality, however. I don't think I have ever read where someone praised the quality of their Corona mill - the quality of the crush, yes, but not the quality of the manufacturing of the Corona mill itself. This is not true for roller mills. Also, I have read about people who have gone from using a Corona-style grinder to a roller mill and who loved their new grain mill. Conversely, I have never read where someone said they changed from a roller mill to a Corona-style mill and thought it was an improvement over the roller mill. I am sure you will now hear about the great quality of the manufacturing of some Corona-style mill from one of its users. I am not so sure you will hear from a former roller mill user who now prefers their Corona-style.
