Same as in the last thread, because you are all retards that like to bicker about the same shit in every thread:

If you can wait: Wait for Tundras. They are basically the same as HTC 3.0 trackers, but smaller and cheaper. The dongle (multiple trackers and only 1 dongle) is a huge QoL thing. Good luck having patience as nobody really knows when they will finally be open for public.
If you can't wait get the HTC 3.0 trackers. They are exactly the same tech as in tundra, but bigger and a bit more expensive. 1 tracker = 1 dongle, so prepare to get a good USB hub as well.

If you got no base stations whatsoever, get them. Every other solution is shit.
SlimeVR is floaty af, japanese 3-cam-tracking thing is nice but you slide around like a mad man.
You will pay less, but after you buy those "cheap" alternatives you WANT good fbt and pay for lighthouse and lighthouse-trackers.
That is just the way it is.
