Londinium Vectis owners: I need you

Hey guys, i'm in the thinking process for upgrading my Profitec Go.

My brain is jumping around and considering many machines. On one side i really like the Meticulous but the uncertain delivery time, project youth, no steam are making me to reconsider.

I've taken into considerations also something like the Wendougee Lita, but i really don't want another vib pump machine. And i am unsure about all that interaction through screens. Certainly playing with flow and pressure would be fun, but how often would i do it? Not sure...
So, i rediscovered a machine i was used to like: the Londinium Vectis. I've read super positive comments here and on discord on its quality, durability and simplicity. I have a few questions though that maybe owners in here can answer:

1. Does the group fits normal E61 portafilters?
2. How long does the heat up take (220v, if it matters)?
3. What is the maximum yield more or less?
4. What is the peak pressure of the spring?
5. Experience with step down baskets? The extra head space would increase the possible yield?
6. General comments/recommendations?
7. How has been your experience?

Thank you in advance!
