Given you started the thread I'm very upset by your spelling of espresso
This is not a direct response to you but my experience of grinders over the past couple of month. I recently went from a Sage Smart Grinder Pro to a Niche and whilst it is a wonderful thing and I'm really pleased with it, on a pragmatic level it's not worth 2.5x the Sage 'in the cup'. It is worth it for the build, the workflow, the sound, the very fine control, all of that is great. The espresso it makes does have improved flavour and texture and it makes dialling in easier, there's less waste etc etc. But the Internet would have you believe it's night and day, but I think it's very much a case of incremental gains to me.
This thread has proved really useful over the past 18 months and from someone who went from drinking very little coffee to really enjoying the whole process it's been a good hobby to pick up.
