As collectors (or scalpers/speculators ), I'm sure we've all been burned or bummed out by some deal we got. What're yours?

I'd have to go with stupidly falling for the "well, you may never find it again" line and shelling out $35 for POTF2 Lando Calrissian. Ugh! One good thing that's come out of that atrocity; I have NEVER been burned since.
