Notes from Casey "The Coffee Guy": You have probably taken a look at all the different roasters we offer and your brain is spinning looking at all the features and options. I'll make it simple on you. The Nesco roaster is a nice little unit. It takes a little more space on the counter and takes a little longer to roast (about 20-30 minutes as opposed to the i-Roast's 10-20 or the Freshroast's 10-15), but it doesn't produce any smoke. It's a bit quieter too. I recommend this if you are getting it as a gift for someone who has never roasted before, or if you like the idea of having no smoke in the roast - just wonderful roasted coffee aroma in the air. One downside is that a little chaff (a fine paper-like skin that comes off the bean as it roasts) is left in the roasted beans. You can get it out by walking outside and blowing into the roasting chamber after a roast. The chaff comes right out.
