You can get a Quest on ebay for less than $200 (in North America at least) which makes it cheaper than a used Go + Nolo with better visuals and MUCH better tracking.
Sorry, this is not a good recommendation.
I already got rid of it. Also, my firmware(s) were up to date as well as software and my network setup was optimal. This thing is just no substitute for real 6dof VR even though it damn near costs just as much.
