Man, I think you are gonna get taken.
They'll buy it cheap and put it up on mod-traders FB group for $200-300 each. Hell, the K-100 clone (that isn't even close) sells for $35-45.
Maybe you just don't think much about the value of collectible things, but others will and they surely won't tell you how much it is. People on the Internet are wolves. ;-)
So, old = shitty? That's ridiculous as they are collectible mods. Classics even. You won't see them again because they are not made except for the Grip and that is over $200 new.
People don't sell those often.
You asked me, and I told ya what I thought they were worth. I wouldn't stoop to offering such a pittance as $50 for a special edition black Empire with the stand. I remember when those were made...people went insane and they sold out in a day.
Just because I could offer that lowball of a price, doesn't mean I should. If you sell those that cheap, I should buy them since I had first dibs.
I just wouldn't have the cash until after my birthday on the 31st....so there's that.
