I'm curious as to whether this would really make better coffee. Is fresh roasted from green beans a better cup? Is their regular roaster worth getting vs the digital one? Do green coffee beans last longer? Where do you get green coffee beans? Does anyone have firsthand experience with this product that is not associated with the company? So far what I've learned from the faq, unrelated to my original questions: A gas heater source is preferred but not required (particularly single burner camp stoves work well). Apparently smoke production (release, capture, generation?) is one of the most important variables. (Which is something this addresses?) So far that's what I got. The rest of the faq seems more concerned about taxes and shipping. If someone (or an employee) with personal experience can answer the first questions, it would be appreciated. My wife enjoys her coffee and her birthday is coming up soon. :)
