You can always give them to me! LOL.
Yeah I feel ya though, I am in the same boat. I really want to buty a HPI 5B, so I thought I would sell off a bunch of mine since I have in them in the hundreds, I would almost have to give them away so they all still sit in stacks, and stack, and stacks of boxes in the basement.
Anyway, good luck selling yours buddy. If you have a lot of 1:24 you may want to try gomotorbids.com they will buy entire collections, but they really don't want 1:64
BTW heres a pic of what I did to that ol CZ4
