Probably because it's steam driven, not pump driven, if you want to get technical. I'd get it and enjoy the great coffee it's capable of making.
I had a similar machine for years before getting my current machine.
Heck, it's been said in these parts recently that anything less than a Silvia isn't a "real" expresso machine, but I sure enjoy the fake expresso coming out of my Baby Gaggia every day, even if it's "missing stuffs"
Enjoy your machine, congrats on 5 years, and be very skeptical of stuffs you read in these threads.
