A lot of good thoughts in that post.
First, every couple of months or so this thread (or one of the pretender threads) circles back to a fundamental law of coffee: it is very difficult, and perhaps impossible, to beat the taste and value of the simple brew devices, like a FP, the moka pot, or a good pour over. It is just true because it is.
Second, I would echo Shrink's very good advice on the La Pavoni. I own one, the 16 cup model in stainless, and you have to really want it....
Third, I agree utterly with your comments about design and the like. The Lido 2 falls into this category, as do Shrink's devices, and certainly the GS/3. I think I described the Lido 2 in a prior post as "the Mac of grinders," and that may have slighted the grinder.
Fourth, in respect of the wondrous GS/3, I am glad I own one, but I would never have paid $7,000 for an espresso machine. I love espresso and think about it as much as I think about anything other than Mrs. Kurwenal, Kurwenal Junior and Princess Kurwenal, but it is, after all, just some ground up beans mixed with water. I expect that I will get to the point where I can pull a triple ristretto on the GS/3 that I cannot pull on the Rocket R58 v2, but I am not there yet and the GS/3's cost is sort of embarrassing, if you think about it, for both the seller and buyer. If Ian Banks had before his untimely death written a Culture novel where espresso machines were ships, I think the GS/3 would be an Eccentric ship, at least.
Fifth, I would not recommend the GS/3 as a starter machine, or even someone's 3rd or 4th machine. In full auto mode, it produces phenomenal coffee, easily beating the Gaggia Accademia (which sits in an upstairs room in my house in case I need a quick coffee) and any other so-called super-auto that I have used. But, that much better? Not really. Not unless you get in and futz with it.
There are many great machines out there. As you noted, the advice to spend on the grinder and a regular source of fresh coffee is right, absolutely and fundamentally right.
And, there are other, better perhaps, options that hit the design mark as well. Check out
this machine, for instance. I have never owned one, but I have come very, very close to buying one. Supposedly, it makes pretty good coffee. And, an online friend on a coffee forum swears by
this beauty.
So many options. Only one mouth.....
