I have the BC2. It's too small for us now & I may upgrade to the BC5 later this year.
It has been a fantastic roaster.
Got thousands of hours on her with minimal issues. Just basic maintenance. Randy the BC owner & his customer support has been the best.
I did dozens of hours of research before buying the BC 4yrs ago.
It's almost have the price of the MillCity roasters & they are or were nearly the same design & both made in China. - Cheers
