I have been using Open Office Draw for about 3 years after watching Nathan's Youtube video a couple of times. I will never be an "Illustrator" or reach the level of map making that the program is capable of but it is a 100% improvement over my hand drawn maps and cut my map making time dramatically. I can make a basic 5k map in about 30 minutes. Maybe another 30 minutes tinkering around with it to be sure it is descriptive and correct. It works for me.
