Unfortunately not really. Headsets are expensive niche items that the chinks can't really do yet. 
The quest 2 is good, but you're forced to run proprietary facebook garbage.
Anything between that and the index isn't really worth getting, proprietary or otherwise. It is a lot of money. 
You could look around for some used Vive headsets; while it comes with HTC software it's completely unnecessary and is just bloatware. Keep in mind that a vive headset is crazy outdated and is pretty much a waste of money compared to the index.
