Hello Paul, sorry I did not see your post earlier. I went to the Artisan 6. It's a much larger roaster thats for sure, however they are coming out with a smaller model as well for those who do not want to put that much into a roaster. I got mine without all the whistles and bells on it, I essentially am roasting outside, I don't need a chaff collector, the piping and fan etc and all that stuff that comes along with it so the unit was significantly cheaper that way.
I can reliably roast as little as 8 oz in the thing and I have done batches close to 8 lbs. The unit is VERY responsive, being electric, in that if you want to make an on the fly tweak, you just turn the power knob and in a few seconds, your change is there, you are not waiting 5 minutes for the heat to go up, or down as it may be. I love it it works really well.
kelpdaddy thats the thing though, I don't expect to have to play games with my roaster to get it to work right. In your case yes the temperature is a bit extreme, but in a room that is say 50 degrees? or a bit more to have it do the same thing, that's unsat.
