It drives me nuts!!! How simple sample roasters are...and they cost $6,000! Man and starbucks gets you angry?! You guys should focus some of your anger at the sample roasters manufatures! I personally wouldn't use the electric cooker...I like gas better than electric..also you would have to re-do the motor for the drum...I have seen them turn and it isn't fast enough to keep the coffee tumbling....the grill would work...no air flow though...but you you could just put the drum over the flame...I used a javitz berns from 1918 that didn't have air flow either..the only problem you might find is cooling the coffee after it is roasted...you will need to run a fan on the side of the grill with a graiting over it...man now I want to fiddle with my grill...oh well keep us posted I am interested to see what you come up with. Oh yeah and on the drum...guess you would have to use the some kind of mesh drum? Or how are you planning on checking the status of the coffee?
