>What's the best bang-for-your buck setup at $600 or less?
$300 Quest 2
>If it's an Oculus of any kind, is there any way to not get Zucc'd yet?
Unfortunately not.
>How bad is PSVR for PC use?
Pretty bad, but it's supposedly at least somewhat usable if you can manage to clear the initial hurdle of getting it set up.

Used Vive or used Odyssey+ is your only cheap option if you don't want to get zucc'd.
Reverb G2 is right at $600, but I wouldn't really recommend it unless you're planning on mostly playing sims in VR.
