David...I'm not sure as the SCAA is geared more to professionals and such, that you'll get a lot of "hands on" time. These folks are there to do business with others that do business, and so forth.
My wife won't touch my setup, even though I've explained the process, bribed, etc. Realizing you won't be home a lot, I think either the HX machine with the best steaming specs, or the La Spaz is the best choice.
Of course, to complicate matters further, you could get a used manual lever such as an older (1981-91) Olympia Cremina, which steams like a demon. 10oz of milk stretches to 14 and is ready in less than 30 seconds.
Total cost for a perfectly refurbed Cremina...less than 1k. leaving you $500-600 for the grinder of your choice.
Don't forget a proper tamper, milk pitcher, brushes, etc...another $100-150.
The Cremina is a classic, Swiss made gem. Much less maintenance is necessary.
The only caveat besides a bit of learning curve...not that bad, really....is that it is not designed to be left on all day. However, it is ready to pull shots in around 10 minutes.
Now that I've really got your head swimming...
BTW, the reason many folks have multiple machines is the reaon you've had SO many replies here. Simply, there are many different ways to climb the same hill, at least when it comes to good espresso drinks.
