One thing that is sometimes hard to remember is that professional equipment often gains a reputation for greatness because you still get a decent cup even if you "mess up" everything along the way. The "sweet spot" for commercial equipment is often much wider than that of pro-sumer equipment, which is then again typically much, much broader than most of the sub-$1000 SBDU units ("The shots I got the first week from my <E-61 HX machine> were better than any I could ever reliably get from my <Silvia-esque machine>").
So, to answer your question, I think it comes down to that age-old dilemma, how much are you willing to spend? It's something of a zero-sum game -- you can learn to pull an occasional good shot on very inexpensive equipment, however, unless your barista skills and senses are already well developed, it will take you a long, long, long time to be able to do so, even longer to do it twice, and maybe never reliably. On the other end of the scale, I probably could teach most anyone to pull a decent shot on a current La Marzocco and a Super Jolly or better grinder in just a few minutes.
I'd say that, "Given a reasonable budget in both money and time, and access to good quality beans, you can easily pull shots that are comparable to or better than most non-high-end coffee shops."
(Can't compete with an attentive, expert barista that is pulling hundreds of shots a day on the latest equipment with the best beans at their peak.)
