defacto set of gmap modules?

Getting started with creating google maps in drupal, I found an overwhelming number of modules (many of which seem to duplicate eachother?).

My premonition is that gmap, cck, views, and location are the defacto 4? I'm also seeing gmap_addons, gmap_module, cck_gmap_address, gmap_lat_long... ugh!

Any take on the best-shot approach to creating a simple map with push-pins representing nodes?
