they probably aren't what you're looking for, but i'll throw in my favorite flangers anyway:
1) hoax: this is the flanger to end them all. a fucking work of art. nearly impossible to use effectively in a band context, but hey, who says art has to be useful?
2) boss hf2: this one does a really cool jet-like flanger without being too cheesy.
3) frostbite: i think it's an ada clone? real cool pedal, very warm sounding, versatile and intuitive once you get the hang of it.
