Whoo, I found a source for all those old knockoff combiners that used to be all over eBay and Big Lots! I hope these aren't the undersized ones but I don't think so. They're $17.85 shipped.
He has Devastator, Landcross, Abonimus with technobot parts, Computron with Abonimus parts, Broadside and Blitzwing 2 pack, Liokaiser, Defensor, Bruticus/Baldigus, Sixbuilder, and some other robots I don't recognize.
All the classics! Man, this guy has thousands. They must have made a ton of these sets.
I hope this helps someone who wants these.
