You could not find a better place to share your issues (I would say not only for coffee, but coffee in particular).
Ironically, when I was refurbishing my first machine I was regular at Coffeesnobs.com.au and received tonnes of help with a machine that was very popular there.
Dave is the person who consult(ed?) Lelit on several of their machines, all turned out to be market success and if he says something, I never doubt it.
With your experience and resilience you will be fully capable of sorting it out on your own with all the help from this place.
PS My wife and I we love Australia, it is just a bit far and coming down under takes a bit of preparation and planning.😀
