What is the best way to manage GPS data with a PC? - pc gps map software

I have a Garmin eTrex GPS which is not shipped with the software, but has a USB port for PC interface. What is the best way to get my waypoints, tracks, manage, etc.? Garmin has a topographical map software version can be purchased separately, but is expensive. You actually pay for detailed maps, and I do not need. I just want to go my own waypoints on the map.
