So in the next year or so I am gonna be buying a valve index and 3.0s so I already have some stuff in my cart like a fan for the headset and some other stuff but is there anything I should get that is a need?
People will say try the quest 3 I have but I don't really like it so I am looking for something but if you have any ideas let me know besides the valve index and no I am not buy the frame.
And how much do you think I should save and where should I buy it from?
