Yeah the DeLonghi is what I also have my heart set on :)
Now that you mention it I don't think I have ever had Java beans either.
I've had all of the ones you mention, and I really like Jamaican Blue Mountain.
Also have you seen the Super-Veloce espresso makers? They're designed like V12, V8, V10 Italian racing engines, and they can cost up to a half a million US dollars. I can't even understand who purchases those.
