Thanks for the great reviews and the passion that drives it!
I used to have a Silvia and a Mazzer Mini, which I sold about 8 years ago, and didn't really have espresso at home since then.
When walking around Baltimore the other day, I went into a "roast your own coffee" place and the owner poured me an espresso from a La Pavoni lever machine. It was a sign!!!
I went home and started researching lever machines. I came across the Flair, and ordered one. I'm so glad I did. It makes great shots.
For anyone thinking about getting one...do it. My process involves heating everything on the stove while I prepare everything else. The setup and cleanup is really not much more involved than it is for an AeroPress.
Now...I need a better grinder...
