Before I purchased the Ambex, I priced the IR3. Delivered to my door, it was a little over $11,000. The have a lot of "extras" that can really increase the price. The ad is gone, so I did not see what type of duct work it included, but it can cost a lot!
I just got back from North Carolina where I was allowed to tour the Port City Java roasting facility. Their roaster is about the size of my garage! It is a two bagger.
