Source of used software for Magellan handheld

I'm looking for all three. I'll give Ebay a try, but I was hoping to find something cheap.

Are you interested in software to maintain waypoints and routes, download topo maps, or to track your movement in realtime?

Have you tried searching on ebay with the terms "magellan software"?

I have the Magellan SportTrak and was surprised to learn of the high prices for downloadable software. Does anyone know of an inexpensive source or if there is shareware available? Thanks.
