I bought this machine for my wife for an early Christmas present and she absolutely loves it. We bought the bundle (which came with the electric frother). It is very easy to use with a wide variety of coffee strengths and types to choose from. So far my favorite capsule is the Roma which has a strength rating of 8 (10 being the strongest). The Ristretto is the strongest which I enjoy as a Cappuccino or a Latte.
It produces a very good crema for all strengths (at least we think it's good). Several of our family and Friends raved about the machine at a recent dinner party and all were very happy with the coffee we served them.
The folks at William Sonoma were very helpful in demonstrating all the features of this machine.
