Too many newbies spend $1000 - $4000 on prosumer espresso machines, expecting their new toy to produce God shots. But it's not the machine that makes great coffee; it's operator ability/knowledge, paired with good beans, a good grinder, and a properly tuned espresso machine that makes good coffee.
Same with a camera and many other things.
On the other hand, If someone knew they were going to be very serious long term about espresso, why waste the time and money on a lower cost machine that's just frustrating for someone who has high standards and really takes the time to learn?
In Peter's case, I think its good he got a machine that won't be frustrating.
That is a good point. If that is the case I say skip the Prosumer and purchase a used Commercial then. I cannot compare any of the prosumer espresso machines I have ever had to any of the commercial espresso machine I own or have owned. The commercial machines have larger boilers, which allows you to pull more shots for yourself, family and friends, they produce locomotive amounts of steam, they use commercial grade parts that are meant to pull 100+ shots per hour (so when you are only pulling 2-5 shots a day they should easily outlive you), the added convenience of either running through direct plumbing or a 5 gallon bottle and a Flo-Jet pump, and have the real capability of being left on all day versus prosumers who claim this is okay when this is simply not what they were made to endure.
Prosumer machines just spell H.e.a.d.a.c.h.e. to me. I have had several and more stuff broke on the 4 prosumers I had then all of the other machines I have ever owned combined. They have a mishmash of home consumer and low grade commercial parts under their hoods, and are quite unreliable when compared to commercial machines.
If big and burly is a must, I would purchase a used single group commercial machine and outfit it with a PID yourself. I have seen single group La Marzocco Linea's for $2k on craigslist. If you are not in a huge hurry you might want to look into this option, as you will never want to upgrade and will simply have one of the best machines ever made. I am drooling right now thinking about that setup with a PID!
