BigScreen makes a vr headset that is Index compatible, about 150 grams, higher resolution, custom removable/swappable face cushion, and custom removable prescription inserts. Costs about $1000 USD for only the headset. It also doesn’t have AR passthrough. If it cost a little more and had AR passthrough, I would be saving up for it now.
I’ll be saving for another year or so for a VR set. Hopefully the next gen will have the features I’m looking for.
