Good job. I am a coffee addict but I've been making my own espresso-based drinks for decades, still with the same machine, a Gaggia Baby (middle-of-the-pack home espresso manual machine), for much cheaper than any coffee shop, and much better IMO. Most friends who come visit now forego the beer or wine and go straight for my coffee. I have not figured out the price per serving, but I am darn sure it is under $1 a cup. I'll say up front that I make espresso at home because it saves me time. By making it at home, I get espresso that tastes better (to me) than the best shops I have access to, all day every day. At a 30 minute round trip to bike to those shops that produce the kind of quality I want to drink (but not the kind of variety) I'd spend over 12 hours a week just getting good espresso. With this kind of equipment and beans at home I spend about 4 h/week. Irrespective of how I value my time, I don't have an extra 8h/week to spend getting espresso. Plus coffee has become a very interesting hobby that goes well beyond drinking it. And a few months ago, I made a cappuccino for one of my friends who only bought coffee when it was on special at $4.99 a can at Wal-Mart. You should have seen the look on his face. He just forked $1000 for his first home espresso setup, a nice Rancilio and a Gaggia grinder.
