I just got this machine as a present and have heard that it has poor grind quality and the tamping mechanism is wonky. If I upgrade to a $200 - $400 hand grinder will I even notice the difference in taste? I have been posting on another forum and wanted to hear what this group thought. I would love to get a Niche Zero but it is a bit pricey for my pocketbook. A local coffee machine repair shop says the Breville grinder should do fine. I appreciate the time you have taken to read my post. I am new and this is my intro.
