I got to play around with this a little bit in Boston. The 2 group would just barely fit in my bays (so doesn't leave a lot of work space) and it's out of my budget, but the tech seems solid so I'll have to keep my eye on if they're able to shrink that down a bit both on footprint and price (or for some future 2nd shop). https://www.duvallespresso.com/fc1-machine
I wouldn't want something like this to be my only espresso machine because with something like this it's too easy to come up with an espresso that can only be delicious on a similar machine (home espresso enthusiasts and the vast majority of shops need not apply) but as a 2nd machine or outside of a blend development context there's a lot you can do with that.
