I've got 2 4k max models 1st gen and another 2nd gen with the pro remotes, ethernet adapter all the bells and whistles. I too went for them on offer
The two providers I have are closed for invites at the minute. I'm awaiting an opening for somebody else so I'll keep you in mind but it's been some time now no mention of it opening up. But I do stress if it ain't broke don't fix it meaning your found provider. Stick with it if it's working for you. I did like some bits of your playlist Italy was working, Netherlands too. With recent raids those were not working elsewhere including my provider.
