I really like these nationals chapter listings:
Pi Kappa Phi - Picture of the USA, state links. Each state link shows the chapter size for each chapter. Wow.

Pi Kappa Alpha - Also a state by state map. Click the state and it pops up the Regional Consultants. Click on the chapter link and the window that pops up shows a pic of their chapter house, mailing address, and link to their website.
