A couple of years ago, Jim Schulman wrote of the La Peppina (narrow 45mm diameter basket, spring-driven lever) that it can hold its own
... against most commercial machines, even though it has an underweight, undersized group and an operator with a total of 24 hours lever experience.

My initial comparisons [of the Peppina] to the Tea were promising. Like the Elektra, it produced less crema, but an improved flavor for the all washed arabica blend I was trying. I got very nice shots from the get go. Since I sincerely doubt I'm any sort of lever prodigy, I'm guessing this is a fairly simple machine to use.
Bear these earlier statements in mind when you hear that "the narrow baskets are a limitation" and take with a grain of salt the statement that "lever machines are harder to use than pump machines".
All three of my lever machines are quite easy to use, much easier than a Rancilio Silvia. (Silvia is probably the most frequently wed and most frequently abandoned espresso-machine-bride.) The Cremina, of my three machines the closest to the Achille in design, has been a very forgiving machine ever since I lowered the boiler pressure by adjusting the p-stat.
When I am duly convinced that it was ill-founded, I will retract my opinion that the choice of 58mm diameter basket makes the Achille less adept at producing singles than are the vintage levers with their narrower baskets. I would note that Dave's (cannonfodder's) initial attempts to pull singles with the Achille tended to corroborate my opinion on that subject. Admittedly, Dave is of the tight-double-ristretto persuasion. It might be fairer to the Achille to have had Karl pull singles with it, since Karl is a singles man.
But my opinion of 58mm single baskets, though not retracted, is in limbo: the picture of the Faema style single basket looked promising; it seems more forgiving than the Rancilio's extremely shallow single basket.
Can we get a picture and some relevant dimensions for the Achille's single basket and some information on what other manufacturers' single baskets are a good fit for the machine? Perhaps the WholeLatteLove sales rep who sings the Achille's praises can provide this useful info in addition to the glowing sales pitch? 
If he wants to send me an Achille to pull singles with, and any set of single baskets, I promise to give the machine a fair assessment on that front.

I have not offended the OP. However, you have called me a liar. As Yosemite Sam might say,
Them's fightin' words! But since I have learned a lot about espresso from you, and since it was you who got me onto the Peppina in the first place, I won't ask you to apologize for the ad hominem insults you've flung my way in this thread, and will treat them as a one-time aberration. I hope you get back to your usual self real soon, pardner.
