Haven't even seen an Elektra machine in person, but I've pulled shots on a Mirage, and it's the most forgiving machine I've ever used (I've worked with Lineas, have pulled on NS Aurelia, various modded FB70s, and a Mistral w/ paddles). I was also told that they are tuned to be used with a very brief flush, and when this is practiced they are temperature stable. From what I've tasted, this is in fact the case. I absolutely love the steam wands and tips on the van der Westen machines (Mistral too). Steam is powerful but controllable. Taste wise, there's more body and middle flavor to the shots, with slightly muted acidity. I'm still convinced that basket geometry, shot parameters, and grinder have a bigger effect on how a coffee tastes than the specific machine type, however.
I'd consider that new Elektra Nino, or Anfim+Search/Robur E/K30 Vario for a grinder. Not having to control dose manually makes for a faster, more consistent, and cleaner bar.
I have worked with a Swift and despised it. They can make wonderful espresso, but it's too difficult to adjust dose. I'd much rather have a timer I can change on the fly, depending on how the espresso is behaving that day.
Full disclosure: I work for a Metropolis wholesale customer, and Metropolis deals Mirages.

P.S. Have you seen the Veloce panels on a Classic (not machined)
body?
