Can any of these work without some idiotic third-party account?
If you’re just talking about WMR devices (and not VR in general), then no, they don’t require an account. The Reverb G2 is the most supported by Monado (and has the best hardware), but I’d try to get the V2 revision. And the cable is a common failure point, so could be an issue with a used purchase.
