I was considering selling my entire collection, because of this crap. It's been going on for quite a while, and doesn't seem to be going away.
The price on that lot is probably, at least, like three times what it is actually worth, IMO.
The Crystalite is the only thing remotely rare. The common figs, mutants, and weapons pop-up all the time.
Wonder what a Sciroid Battleship would go for, if one ever surfaced?
It probably wouldn't sell, actually.
Since it would have a BIN of $1,000,000!
