I have a WMR device and I regret it.
So many games simply do not support it, I’d have been better off with a Valve index that seems to work with most PC titles.
I have HP reverb G2. It has seemed to work fine with everything I’ve thrown at it. Though I’m not sure about the cheaper devices. I probably wouldn’t recommend spending that much on a WMR headset at this point.
But, WMR devices can be found for $75-$150 dollars on eBay. I don’t recommend them if you’re serious about VR. But if you just want a cheap entry point, they work.
