I just got my new Kaldi. The old one got destroyed when a car drove through my roastery. I know the Kaldi roasters are for home use but I really like them. The last one lasted for 5 or 6 years. I even brought it home and roasted 20 batches in 2 sittings. I was surprised that the roasts came out so even and consistent! I added a little cart so I can now got to our local stores and run demos.
