peter, initially i was not planning with going with a 10 kg (too big?!), but if the price is right and the hardware/brand is good, then this may be the "opportunity" that i was hoping would come along. i have incessantly read on most of the top brands this past week, but have crossed several off my first-roaster list due to the lack of value to price. i know that ambex is a quality machine, but i cannot afford to make any mistakes on this choice. i want to make sure i "nail it" out of the blocks, such that if i stayed small (<100 lbs per week) i wouldn't have any regrets. what i am finding (from online reports) is that there is wide divergence on build quality. i now know that ambex is quality built, serviceable, and produces good/great results assuming the proper dedication to the learning curve that would be required. just considering the volume of subjective info out there, it makes this decision difficult. is anyone aware of any in-depth objective comparative studies on, say, the top 10 commercial roasters... kind of like a consumer reports?
