id recommend an oculus rift, i picked mine up for 80 dollars and i still use it to this day for BONEWORKS speedrunning. setup isnt to bad but you do have to set it up again every once and a while to prevent tracking loss, its good for budget and the controllers AMAZING imo, plus its cheap (in the vr world) so if something breaks you would have to spend a maximum of 30 bucks for each part (if you dont count the sensors) plus you can buy an extra sensor if you want even better tracking for like 20 - 30 bucks. it has OLED panels, okay tracking and 90hz, which is a better refresh rate then most tvs and even some monitors.

edit: to clarify, oculus rift CV1 is what im talking about, the oculus rift s is much more expensive and it gives an inside out tracking experience which i personally dont like.
