I think the Rift S is the easiest and most cost effective option to get into VR right now. The other option worth considering is the Quest, which can also play PCVR games. If you see yourself liking the mobile/wireless part of the quest or the hand tracking, it might be better. It does have a worse 72hz refresh rate though, so maybe not if you're sensitive to smoothness.

Oh, another thing is that the Rift S doesn't have hardware IPD adjustment, while the quest does. So if your IPD isn't in the Rift S range, might also be worth getting a Quest instead. Or an HP reverb, or refurbished CV1.
