VR is expensive, you either pay with money, or pay with your private data (this is why meta vr is so cheap).

However, I like my HP reverb G2. You can pick these up second hand for basically nothing, under $200.

Microsoft ended support for windows mixed reality with windows 11, but there is a driver on steam that makes it work. Major downside is Linux support is not good. But if you're using windows, that would be my good cheap recommendation.
