Summary: I had read some reviews on this machine and was a little hesitant to purchase it based on some of the reviews by folks that were not able to get it to work like they wanted. After making some espresso and some cappuccino with it now, I have to say, this is a very good machine and easy to use. It makes very good espresso with a nice froth on it. It's possible the folks having some problems with it are not letting it heat up long enough.
Summary: I bought this machine because of the stainless steel boiler. Most cheap machines use aluminum. It's a great machine. Super easy to use...just have to let it warm up for 20 min. Once it's on, leave it on and make espresso all day. The espresso comes out dark and creamy depending on how hard you pack the cup. The foam steamer works great as well. Great machine, definitely worth the money.
Summary: I ordered this machine off amazon.com after reading the very positive reviews on-line about it. The best part was that amazon had it available for just $72 plus shipping (for a refurbished machine). Initially, I was going to order the EC155 (which is very similar), but then noticed that the EC330 was much nicer looking (more stainless) and only cost a few bucks more. Both the EC155, as well as the EC330, received very good reviews.
