I wrote a reply to this thread yesterday (it would have been the first) but it sounded elitist so I deleted it before posting... but:
Take a look at the logo at the top of this page... "Your Guide To Exceptional Espresso." It is towards that goal that lured most of us here as regulars. There are plenty of folks here who spend a lot of time helping newbies and patiently answering their questions. We got the experience from traveling down the long road. We don't guess.. we KNOW that there is no way you will get exceptional espresso (at least not consistently) from a Silvia and a Rocky. It might be drinkable, and it may even be better than anything from a coffee shop within 100 miles of you, but exceptional? Not in my experience. You can play at it, and it will help develop skills that will serve later, but that's about it.
I only speak for myself, of course. I used a Rocky and Silvia for about 7 years before stepping up to a Vibiemme Domobar Super and a Mazzer Kony. Night and day difference between the two. So many of my comments and responses are based on that. Virtually all the pump-driven, single-boiler machines will work the same, albeit not all of them will last as long nor have the same resale value. With Silvia's price point, and the percentage (around here) of users adding PIDs to them, the total cost makes little sense, and so we often recommend stepping up for a little more to get a heat-exchanged-equipped machine. If a newbie comes in wanting to spend "under $500" to get everything they need to make "e
xpresso" at home and later find that $700 is the price.. just for a decent new grinder, and they feel snubbed, disappointed, or are scared away... oh, well. If they come here to be educated, there are plenty of folks here ready to assist.
On the other hand, if they drop in here without some sort of background in espresso and do not take the time to at least read through the FAQs and get pissy when they are directed in that direction, oh well.
This forum has a professional scientist who took ground coffee samples from a selection of grinders and had them analyzed on a scanning electron microscope! YES, REALLY! So when a newbie comes in here and is told, politely but bluntly, that a $325 machine will not make very good espresso using pre-ground coffee from a can and that they need to spend at least $100 for a hand grinder, or at least $300 for an electric grinder, it's not our fault that they now own a burst bubble. Might as well drop into the local Porsche agency and ask if they have any nice, used 911's with low mileage for around $3500. They get pointed towards the discount used car lot. Around here we often point them to CoffeeGeek.com.
If someone says that they have $750 to spend and want exceptional espresso, I tell them to get the best grinder they can afford and a $30 Aeropress, and to save for an espresso machine. If that causes them to be scared off and not participate and learn here, then the odds are that they would have lasted long making espresso at home either. Espresso is not for everyone (See: "Are You Anal Enough for Espresso" Chapter 9 on my website). There are shelves all over the country where espresso machine go to collect dust, and eventually get sold at yard sales or donated to thrift stores. Looking at it from that point of view, we might actually be doing them a favor by scaring them off. Even Starbucks tossed hundreds of La Marzocco espresso machines into bins and sent them to metal recyclers because it was easier and cheaper to train employees to push buttons of super automatic machines, quality of the product be damned..
Scenario: Man walks into an insurance agency:
MAN: I am here for the insurance.
Agent: Did you bring it?
MAN: What?
Agent: The sample.. err.. specimen.
MAN: Yes
Agent: Where is it?
MAN: It's down in my car. Would you like me to bring it up?
Agent: No. That will not be necessary.
MAN: What!? Then why did you have me save FIVE GALLONS?
Agent: We wanted to be sure that you REALLY wanted the insurance.
