Been using SteamVR on Linux using Proton as a compatibility layer with no qualms for a while and I'm feeling inspired to take the jump into FBT. Are there any cheaper options for FBT than the Vive tracker? I found a pretty decent price for some but I'm open to other ideas. No Kinect though, I doubt I'll get it working on Linux.

Alternatively, anyone selling theirs used for a better price? I have no qualms about what you did in them.
