I was also personally tempted by roasting, but I prefer to have it done by a professional, because it's a real job that requires a lot of experience. Finding green coffee is also not so easy and the choice is limited.
On the other hand, I look for some months for another coffee machine, even more "manual" than my Sylvia...
...a La Pavoni with lever. Of course, I want a model with an eagle on top, the Italian elegance !
La Pavoni Italia
For sure, this is not a "press button" coffee machine.
Several years ago, during a trip to the Czech Republic, we went to a bar at Prague, only because we had noticed there was an outstanding machine inside: an Elektra. I can not afford, nor the use, but we must recognize that at the aesthetic level and for coffee machines, the Italians are still very strong. This "steam engine" is finally not that complicated to master, and for a bar, it's really a plus to attract customers.

There are several models and I wonder if anyone has one? the price is not so exorbitant compared to some pinball machines.
