Coffee roaster. Have tried a variety of roasters from air (too noisy) to Behmor ($$$, not durable) the current Gene drum roaster (expensive, and still working after 10 years).
Oven roasting is limited by lack of visibility, inability to hear the all important 1st and 2nd "crack" of the beans, and a method to cool the beans, thus preventing over-roasting.
