Thanks Jeffrey for the information!
That 1kg Probatino on your website looks exactly like what I envision upgrading to after I build a garage (after a deck, after a fence, etc.) I guess that 
backyard shed you put yours in is sufficient for Southern California climate. I'm hopefully planning an insulated, temperature & humidity controlled roasting room for Maryland summers and winters.

I will contact you directly regarding the Hottop CCR.
Thanks again,

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

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.
For a description, see computercontrolledroaster.com
