Has anyone tried this? I am thinking about testing it out but am wondering what the reviews and your personal experience is.

You can download it here, but this is what they are saying about it.

Find and manage all your podcasts on Mediafly download and Sync with Mediafly SyncClient. Easy. Automatic. Free. Download all your podcasts in the background while you work. Your media is organized into Mediafly channel playlists for easy access. Old and expired episodes are automatically deleted. Sync with iTunes, iPods, iPhone. Sync with Sansa, Creative Zen, iRiver players, cell phones, and more (no more need to manually copy to and delete from your devices). Or, download to folders organized by channel for easy access.

So it should work with your Sansa. Let us know if you have tried it.
