Current Model 2003 Diedrich IR3 with Afterburner makes a perfect coffeehouse display roaster - even great for teaching classes. Here is the story. Small chain operation bought this roaster to do in-store demos and do some marketing classes and wanted to have the showcase but used their main big roaster from another location to do the actual resale inventory. What that means is that this roaster was hardly ever used and never did actual production. Now there is a new owner of the actual location running a coffeehouse and really has no desire for this Demo Roaster as they would prefer to use the space for retail merchandising and seating space. That means - this roaster has to go. Look at the photos (taken this July) and you can see even the paint is not worn in the fan area - super clean. This is about as plug and play as possible.
