Devices like the Livio Carmen

I’m looking for a way to listen to podcasts and audio books in the car - I don’t really need a an iPod (or similar) device, because most of my listening is in the car (and podcasts at work)

So I was thinking of a Livio Carmen or similar device - basically a(n) MP3 player / cigarette lighter adapter / FM transmitter in one device.

Anyone have any experience with these?

Related question - are the audio books from in .MP3 format, or some wierd DRM format that only some players recognize? (I usually prefer reading books, but an audo book is good for long car rides - I can only listen to the BBC Lord of the Rings radio drama so many times)
