I have a Huky 500 solid drum for sale that I have modded out. It started life as J tube model, which comes with the roaster. I added the tee and a loading hopper, Dust deputy chaff collector with variac fan airflow control, as well as amprobe that connects to a computer so you can use artisan. I'm asking $1450. Local pickup preferred (portland, OR area) but I will ship buyer to pay for shipping cost.
