Holy smokes Batman! That is a lot of toys hahaha I've never got that deep but I did buy a few originally packaged Bucky O'Hare Toys a while back LOL I'm not obsessed, I swear.

But I know the struggle. My buddy is a big Lego collector and he went through a hard deal with a buyer when he was trying to pick up a Millennium Falcon set (before they re-released it). Guy was being a little shady. He ended up getting it but there were a few stickers missing inside, maybe a couple pieces. My friend didn't mind, he just likes building them and was able to get the piece of some website that sells duplicates.

Good luck!
