Spanning Sync vs. Busy Sync

Spanning Sync is “supposed”:http://addingunderstanding.com/uninstall-spanning-sync-problems.html to sync Google Calendar with iCal, but there are many issues. Busy Sync apparently works better. The big issue is how do you uninstall it. Most Mac apps are a drag to trash, but here, you need to reload the trial and click on the DMG and they have a dedicated application for uninstall there.
