They're all around the same price, similar feature set, which would you chose?

The LMLM is the safe bet as the other machines are unknowns. Myself, I'd go for the new one-group La Pavoni Diamantina. https://www.instagram.com/p/CVYCRQnMP8I/

Nice looking machine. Has more knobs than I'm accustomed to seeing on an e-61.

It looks like two of the knobs are just for show as they accent the (also for show) sightglass.

To be honest, I think that La Pavoni should have used their commercial lever group on the Diamantina and made a modern Concorso La Pavoni Concorso 1 Group Restoration

I guess SMEG thinks that they'll sell more Diamantina's as E-61's.

The Victoria Arduino Eagle 1 Prima is another option; it almost seems that Cimbali resurrected the Faema nameplate to build a competing machine.

I'm leaning toward the Sanremo You. For me I want a group head design much like my Breville 920XL that gives me strict temp control with a start-up to brew time of 10 minutes. Needs to be dual boiler with great steam...I do milk drinks. Needs what I currently lack...precise control with programmability over preinfusion and over the entire time of extraction. Also looking for great build quality at that price. I'd be spending 5K more than my current machine (which makes excellent espresso), so it needs to be worth the expense.

I didn't see anything that said the YOU would be ready in 10 minutes ... nor anything about group heaters that would make that a possibility?

Given the design of what appears to be a three-way downpipe and cover, it looks like the YOU is using Sanremo's version of the E-61 Eclipse(solenoid triggered) group found in some of their commercial machines, but the cover would have to come off to confirm.

oh that's an e-61 on the YOU and not a saturated group? Is the Faemina also an E-61?

The Faemina literature says this;

Ready for use in 5 minutes
- Ready for steam in 12 minutes
- Professional Faema coffee group of the top of the range

So I would say this is anything but an e-61 group. Very much to my liking. 5 minutes is insanely fast.

I also have a feeling that the Sanremo YOU is not e-61...but still looking for confirmation on this.
