The Meta/Quest 2 is a standalone VR headset, which means you don't need a computer to use it. If you're just getting into VR, I'd recommend the Quest 2. The price is decent and the performance is superb. It's my VR headset of choice.
may the road rise to meet you
may the wind be always at your back
may the sun shine warm upon your face
the rains fall soft upon your fields
and until we meet again, may God
hold you in the hollow of his hand
