Hello, My wife and I have run a small cafe for the last 5 years. I want to start roasting our own coffee for our use and retail. I am looking at a 2005 model Ambex YM-5. The current owner says that it has never been used due to an illness that kept their business from getting off the ground. My problem is that I have no idea what it is worth. I have contected Ambex (now Roasters Authority) several times and can not get any response. Does anybody know what this machine sold for new? Any idea what it is worth now with 0 hours of use but 7 years of storage? How do I tell if in fact it has never been used? Is there any issues I should be aware of with a roaster sitting for 7 years? I would really appreciate some help. Some leads on purchasing green beens would be great too! Thank you. shawn
