Comixology has a Batgirl sale for the next seven days. I already have Year One, The Bat and the Cat and The Greatest Stories Ever Told. I'm thinking of getting Batman: Batgirl (1997) #1, Batman: Batgirl: Girlfrenzy (1998) #1, DC First: Batgirl/Joker #1 and Batgirl Special (1988) #1. What do you think? Are any of these good? Thanks!
