Well I can list many, but if you want ones that I've seen little or nothing of, but definitely would like to.
Devil Hunter Yoko: yoko has a really cool suit!
Steel Angel Kurumi: Any chick from this anime would rock!
Apple Seed: What chick wouldn't mind a huge robot as a bf?
Iria: She's an all-around BAD ASS!
Dirty Pair: Not the newest anime, but cool none the less.
Tenchi: Tsunami is a ditz, but is awesome; hardly cosplayed!
Geobreeders: Plenty of choices in this anime!
Agent Aika: Who wouldn't want a lipstick light-saber?
