Assuming you have a decent computer, you can get the Lenovo Explorer VR system for $140 at Walmart right now. https://www.walmart.com/ip/Lenovo-Explorer-Windows-Mixed-Reality-Headset-Black-G0A20001WW/751420233 I've used PSVR, Oculus and Vive standard and Pro. The Lenovo isn't perfect but at this price it's well worth it. I also find it a lot more comfortable than any of the other HMDs I mentioned. X-Plane 11 works great! You can read the text on the glass panels or the steam gauges. The head tracking (inside out, no external sensors) is flawless. FF works on a virtual iPad in the cockpit. Some of that is hard to read. DCS World looks really nice too. The cockpits seem a little more optimized for VR than X-Plane. There is no small text to read, such as the "NAV" button on a G1000. If you're into flight sims and want to be fully immersed, now you can do so for less than the price of an IR head tracker!
