I've got a Mario Kart Stylus that was given away at E3 this year. It is about as big as a normal pen, with a rubber Mario in his Kart affixed to the top. A great stylus for people with big (or normal sized) hands. It also has a string through it so you can wear it around your neck.....if you really want to.
I would like to trade that for the Phoenix Wright Ace Attorney Stylus, the one with the pointing hand at the tip of it.
*edit*
If you have no desire for a very sexy limited Mario Kart stylus, I also have a variety of other games and swag I can trade. Of course, cold hard cash is always an option too
