throughout 12 yrs or so of roasting,the behmor is by far the best ive used,just the fact it an do a pound is nice although to be honest 12 ,14 ozs work a bit better,considering performance, price, customer service,and noise levels are very low with it so you easily can judge roast level by first and second crack,its also good at smoke suppression although you roast coffee there will be smoke,thats just the way it is,but its actually low in the behmor and works as advertised,its just really nice to do a decent amount instead of measly 5,6 oz loads.
