What's the used market like these days?

[Sasq40]

I'm thinking about clearing out my old stuff, not looking like I'm gonna refire anytime soon. Wondering what a fair value to ask for everything is. I have 2 mp40 qd. 3 gen 3 xr30, brand new vectra m2 v2.,vertec alpha skimmer, few reactors, 200ish lbs of rock that have been outside for a year, among various other things lol
