Just thought I'd throw this out there. I still have a MIM Strobo. I also have some tough holes in my collection. Namely...
-Cyborg Ninja (variant "Red Fox" Play Arts Kai, MGS)
-Solid Snake (Play Arts Kai, Metal Gear Solid)
-Fin Fang Foom (BAF, Hasbro Marvel Legends)
-Vision (regular, Marvel Universe)
I may put up some cash as well if anyone can trade any of these things. Pm me.
