I am in the same vote, last year I picked up one at a great price second hand but new in box. It was part of a Vittoria coffee competition prize.
It is a great machine and has some real nice touches. However, I haven't had any experience with other HX or E61 machines. Only real issue is the OPV wasn't set to the right pressure. I have read this is because they have an ECE pod capability and the high pressure is required for that. Therefore, I still need to set the OPV pressure.
Most articles I found in HomeBarista forum from America, as they were mostly sold in America I think (Chris' Coffee sold these machines and did a video/youtube review). I did however find online a presentation for what seems meant for dealers I think.
