I have had a Jura S9 for many years, got it ex demo from Fairfax Coffee and been happy with it. I have had servicing beyond my capabilities done by Richard at Cafe Select , a stand up guy that sells reconditioned machines too - maybe take a look at what stock he has
https://www.cafe-select.co.uk
There are a few other outlets e.g.
https://juraoutlet.uk and
https://juraoutlet.uk
I don't know these, but they give good warranties and have a lot of choice.
Note that, whilst it does not look as fancy as the newer models, and needs a bit more room, the S9 models have twin thermoblocks, one for coffee and one for steam, which may be useful if you want to knock out a bunch of lattes.
Dual or single thermoblock info from here

"The thermoblock is the part that heats the water. Thermoblocks produce two different things: hot water (for coffee and tea) and steam (for frothing milk). To make steam, the thermoblock has to be hotter than it does when it's making hot water (this should make sense if you payed any attention in junior high science class).
If your machine has only one thermoblock, there will be some downtime between brewing coffee and frothing milk. After frothing milk, the thermoblock has to cool down to the temperature required to make hot water. And conversely, after brewing coffee, the thermoblock has to heat up to the temperature needed to make steam.
How big a deal is this downtime? Depends on your needs. If you're going to be making one cappuccino for yourself in the morning, a one thermoblock machine is probably fine for you. If you entertain a lot, where you will be making lots of drinks for people, one after another, or if you're the kind of person that will go nuts every morning waiting that minute or so to froth your milk, then you probably want to go for a dual thermoblock machine."
Anyway good luck, any questions fire away. I looked into "real" machines years ago but had to be honest with myself - convenience counts for a lot.
