I have two of them and although they don't have all the features I would like, it has made roasting a lot easier for me, especially when I am run both of them at the same time. Seeing as the warranty will run out soon on my 1st one, I am thinking of hacking it and running the heating elements off a variac. This should give me more of the control I'm looking for during the roast. I still pull the chaff screen and leave the door open as soon as it enters the cooling cycle on a roast. Besides cooling the beans faster, the machine is completely cool by the time it shuts off, which allows me to do back-to-back roasts. Of course this creates a little mess, but I have a small shop vac nearby to handle this.
