I hope this roaster gains momentum, and gets perfected over time, as it would be the next step up from the KKTO. Having said that, my KKTO is pumping out lots of coffee, and I am very happy with the results. Lots of tweaking is yielding excellent results in the cup. I roast between 700-850g batches, depending on the bean type, with 750g my base line. Buying another roaster in the foreseeable future is strictly forbidden, so I too am interested in your journey with this unit.
