Answering your last question first,  HotTop never came out with their 
higher capacity model. They promised it for years but it never 

I spent several years developing the computer controlled roaster (CCR) 
which was based on a highly modified HotTOp.  It works flawlessly. 
While doing extensive experimentation, I found that the airlow within 
the HotTop is not great.  I experimented with continuously 
variable fan speed and found that it is truly best to leave it at 
full speed all the time.

Although I stopped the manufacture of the CCR systems, there is one 
owner who has retired from drinking coffee owing to medical reasons. 
He is willing to sell his through me as I would need to do a full 
refurbish and re-calibration and then compile new software for it.
