When the Solus Troubles unexpectedly hit us, and it was clear that it was not a short-term problem, I settled on a distro I'd beeen very fond of when I examined it for the "Other Interesting Distros" thread.
In fact, I'm still so fond of Sparky Linux, that it's the only non-solus VM that I keep on my laptop, and update along with my Solus VMs every week or so. It's a little behind Solus when it comes to its Plasma version, but it's still quite usable. It's a rolling release that offers updates more often than even Solus does, and everything I ever wanted to install while I was using it was available as a .DEB file. I was able to set it up exactly as I did Solus, it had no problem accessing my NAS, and left nothing to be desired. There's even a friendly and helpful forum, much like Solus'.
So, if Solus went away suddenly (again), I could maintain 99.99% of the same user experience with Sparky Plasma, and do it with very little configuration.
