One of my sons bought himself a Oculus vr & spent a lot of money he had saved up to buy it when it first came out - a few years ago... he was over it in a short time as there weren't that many games available to the system. Perhaps they've made more games for it, but he has lost interest.... He did like it for like the month he played it.
I would suggest to buy one used & try it out first. The price dropped on those original ones within the first year.
