Where to find City/State/Zip database

[digitalv]

Does anyone know where I can get a database of cities, states, and their associated zip codes? USPS.gov has an API that lets you query their system, but I'd like to get the info into my own database.

I got them from here: 2004 First Edition TIGER/LineŽ Files [census.gov]

But they contain alot of info. You may want to look here:
1999 ZIP Codes [census.gov]
