ive used one and i thought it was a good machine but I like the build quality of the ECM better purely for aesthetic reasons - Ive owned a few machines in this bracket< Bezzera Domus Galatea (ok was quite a bit more expensive when I bought it) and a couple of BFC's which were excellent - but in the end I settled on a second hand semi commercial single group because of the larger boiler capacity - which means that I can put out more coffees per hr if I need to just a personal preference, is all - still, you're not going to get a bad coffee from the machines that you're looking at in that price bracket, and. if you're anything like many on the forum,. you'll probably turn the machine over in a few years anyway - in which case corrosion shouldn't be an issue good luck with whatever you decide ACG
