If and when a new rare costume/furniture thingy comes out what would you trade: Post!

[pokemon_master]

I always what until a cool (but expensive) costume comes out so that I can trade it to someone for something rarer (In fact, I traded a full cowboy suit for teleport magic).

So my question is: how much would you trade for something cool?

My answer: I was going to trade the following for a candy cauldron once: (note: I AM STILL LOOKING FOR OFFERS!).

A green number generater, the full halloween set of furniture (minus the Cauldron) and a diver's suit with helmet. (this was before the suit became untradeable)
