okay, this should not be this hard to find.

for my tech-savvy peeps: i'm looking to put a map on our site of all the cities worldwide where people have our hoops. i've tried to use a few free online mapping services, including Google Maps, and i'm tearing my hair out. are there any you'd recommend? looking for easy to use, ability to customize the color of the "pushpins", and can save the content for later so that i can put new versions of it online periodically without re-entering hundreds of cities.

help?
