I have a cereal killer 2 roller and have had no issues with it. It is the first mill I have owned and I like that it is adjustable. My LHBS has a MM3 and I always got good crush from that as well, but had no control over gap settings. Having an adjustable mill allowed me to get what I wanted, and I really have not adjusted in the last almost 2 years. I seriously looked at the JSP after hearing so much good about it on here, but found a deal on the cereal killer for $99 shipped: tough to pass up as a first time mill buyer. Only wish would be for a bigger hopper, but whenever I get around to it, I can work something up for it. The 7 pound hopper is working great for the 3.5 gallon batches I have made so far this year down from years past when I always made 5-6 gallon batches
