>not enough room to make motion tracking worth it
VR isn't worth it without motion tracking. You need MUCH less room than you think to do motion tracking - One person here has VR setup in the cabin of his fucking 18 wheeler. 
Additionally, thanks to corona there will be no rift S back in stock for like a year. 
Next monday (tomorrow) indexes are coming back in stock. Grab an index tomorrow if you can. If not you will not be entering VR for a while.
