WP Google Maps
This is a usable map plugin among the many restricted lite versions that allows you to attach maps to your posts or pages.
Comprehensive Google Map Plugin
This is the "other" usable google map plugin that is really easy to use and is not tied to posts or pages. The only problem is that you can't save your maps, it just creates a shortcode to insert. If you need to modify anything later, you have to start over, If that is not a problem, this is the plugin you want.
