I need these things loose. Though if you can find some stuff MOC, I might be willing to take a look. And Eriktheghostbuster, I don't want those links

You may be able to get some of the packs fromn this guy. You may have to buy some of the figures. I know he is selling the ghosts seperately. You go to www.mctoystore.com and click on action figures #2 Pee Wee to Willo and scroll down to the Real Ghostbusters. I know he is selling like at least 3 different sets of 4 ghosts for like $6 each. Hope it helps.

Thanks, that helped alot. With that, I'll have a complete 1st series, almost. :s
