I only now saw this thread, but I've been doing espresso and home roasting for quite a while now. I am on my 3rd setup, upgrading as I go along over the years.
My current home setup is a behmor 1600+, I have gotten really comfortable with Sweet Maria's Espresso Monkey blend which I like.
My grinder is an ECM S-Automatik 64 which I have really liked once it had a good amount of coffee through it, and my machine is a Rancilio Silvia. I'm saving up for an ECM classika PID. I wanted to stick with single boiler with e61 since I only do neat espresso, no milk or anything added.
I currently use a bottomless portafilter in the Silvia with a triple basket. I have the ECM grinder set to dose 21g of coffee, and then I weigh the shot to 42g since I like a 2:1 ratio.
I am also into woodworking, so I've gotten into making new handles for the portafilters and tamp, as well as a new lid from spalted maple for the grinder.
My previous setup I brought to work with me, a baratza preciso which I single dose 16g with. The machine is a Saeco Via Venezia with a narrow double basket, and I also do a 2:1 with that.
I've been using the Behmor for a while and I really like it. Before the Behmor, I used the Nesco Pro coffee roaster with the mechanical auger. It worked well enough, but could only roast 4oz of beans at a time. I worked that to death though, so when it was done I got the behmor.
The behmor definitely can't do a dark roast (I have been doing full pound roasts lately) at the highest programmed setting, but I don't like my roasts beyond city to full city anyway. I haven't experimented with the manual modes yet, though at this point I doubt I'll do that in the near future.
