I've got a used one with the latest upgrades; but have only used a few times. There are quite a few options as you are probably aware. My kit came with solid drum, 72 rpm motor, LPG stove, vent bowl attachment, extra fan/screen/funnel, and m.e.t. thermocouple. The roaster comes standard with a digital BT thermocouple and analogue ET thermometer and that's all I would need. Many US users are happily using Artisan logging software and with the Phidget 1048_0 3 thermocouples can be tracked. You can drive the roaster with ROR which is supposed to be really cool. So what do you order? Perforated or solid drum, 48 or 72rpm motor, etc, etc? I would at the minimum order: basic machine w/drum of choice, second motor with alternate speed 48 or 72 rpm, vent bowl attachment, stove, and extra funnel. On the flip side with the Artisan/Phidget in mind BT/ET/MET thermocouples would be ordered. The Huky can roast a full pound to first crack in 6 minutes with the standard stove so there's plenty of power. Venting on the Huky is a little tricky as the vent bowl pipe is 2 1/2" and pointed down at a 45* angle. A vacuum cleaner hose fits the opening, finding a flex aluminum hose would be a better solution.
