Valid points.
Re the grinder, I had only just purchased the STPK 38 because I wanted to bring the Gaggia out of storage. Paired with that it’s fine, and I do understand it doesn’t make sense to partner it with a much more expensive machine.
Perhaps my want to go to a very good machine is premature. I may be perfectly happy with the Elizabeth and not feel the need to upgrade.
Thanks for your reply.
