So far, I've gotten:
Kiel, 3 GX (sold one for 50mil), ranger, 2 SC, and two maestro hats among others (can't remember). Besides the Ranger hairband, I still have yet to get the other two I really wanted out of 14 tries so far: RG and AB. >_<
I just wish some of the hats didn't look so...feminine on male characters.
EDIT-'Focus Beret looks the same as the Green Beret.
The reason the hats look feminine is because they are designs based on touhou characters and Touhou is 99,9% female cast
