I've home roasted for over 7 years and continually vascillate between giving it up because it's a
hassle on one hand and the inability to get great coffee locally 100% of the time. Just this week I dumped a pound of local
professional coffee as it was flat, boring and a complete waste of time.
The original HotTop as stock is tolerable for espresso. The programable maybe better, but it's almost a kilobuck. Some like the GeneCafe. Either of these is going to be 3 to 4 RpW. Including setup, between roast cleaning and cooling, and teardown, that's about 3 hours on the HotTop.
If I wanted to roast 1kg or more per week, I'd look at a $ample roa$ter and give the excess to my friends.
Some like BBQ drums, but that might be a long winter in Helena.
There other options like Stir Crazies and the Stove Top that handle the quantities, but they are bit less automated.
