Wow, I had no idea Violent made a trigger for them. huh.
I'd say $75-$90 for all of it. if you part it, maybe you can get up to $100-$120ish. (for all the upgrades on one working wrath.)
I see stock ones in full selling for $50, so I guess something in between there would apply to the eyeless one.
Your best luck would be Ebay or Craigslist.
With some quality photos, you can easily overprice and sell everything
