sacguy71 - there’s also the Londinium machines if you fancy a lever machine. Although it’s 58mm group - so VST baskets, tampers etc and other accessories will fit, there’s no measurement and feedback like the ACS machine. The ACS machine, sporting a La San Marco style group (which is 54mm I think) has a heated group, two boilers (steam/hot water, brew) and temperature control and monitors for each of them, so all individually controlled, as well as a pressure gauge at the group. The Londinium machine has none of it, so it’s all guess work and “magic” as you have no idea of what pressure or temperature your coffee is being extracted at. It’s said to be very temperature stable (at god knows which temperature, mind) but you’ll struggle to find measured real world evidence to back those claims up. The same goes for the other two machines to an extent (Profitec, Bezzera). With the ACS machine, it’s all there in front of you.
