I will be a PNM this fall (yay! finally) and have surfed all of the NPC websites since joining GC. I have been most impressed by:
Theta
Tri-Delta
AOII
Alpha Xi
KD
Phi Mu
These are the ones that have stood out in my mind. They were all entertaining, very technologically-up-to-date, and very easy to surf. I also learned a lot about them.
