I usually edit an existing one. Wikimedia Commons usually has quite a few good images to start with. Then use a program like Gimp or Photoshop and edit away. I use photoshop so I usually add a layer where I add and remove borders, that way I keep my base image clean. I use the paintbrush tool for both, using the colour of the land masses and paint over borders and white or black, depending on the base map, to draw in new borders once the old ones are gone.

To fill in countries for location maps and such, I usually copy my background layer and border layer, merge the copies, and use the magic wand tool to select the country in question, then the fill tool with the colour I want.

Hope that helps.
