MediumRoastSteam I have seen, over the last 1.5 years, you don’t need to own a machine! 😊
@fwx I have never used either of them. But, I know based on members experience, Mara X is a lovely machine. You have a decent grinder. With your budget, you can buy Liz, a nice and a compact DB. If you can stretch a little, ACS Minima from ACS direct. I do not know if the prices of the machines have gone up because of supply side bottlenecks.
Please read the threads on ACS Minima. MediumRoastSteam does own Liz.
Your water is no good. You can go the mineralised RO or distilled. There is a thread on Scuma RO. Please head there and message the owner as there is a good deal going on. You may benefit from that. Another choice is getting a zero water jug and mineralise it.
