I use a cheap little SanDisk and it works okay. Sometimes it has problems with putting the parts in the wrong order, but you reset it and it works fine.
Creative Zen Mozaic works great for me.
I'm using a Creative ZEN 8gig that I'm very happy with. (About $75.00 on sale from Costco online.) Easy to use. Can download both MP3 and MWA formats. Have enought space with 8gig that I have 7+ books at a time. I just delete when finished.
In my vehicle, I use a SoundFly FM thingy (can't remember what it's called) to broadcast the books to channel 100.1 on my car's FM radio so I can listen there. Plugs in to cigarette lighter -- OK, I know there's a better name for it than that, but what is it?
Oh, yes -- Even if ZEN is out of juice (battery charge) the SoundFly will power it so I can continue to listen until I can connect ZEN to a computer with USB and charge it up.

My daughter loves listening on her iPod. She loves her iPod for her music and not having to have something different is great. Before we could put WMA titles on the iPod, we had a different MP3 player just for audiobooks. It worked okay, but was a pain to have to have two devices.
Now, she can go from music to book to music when she is on a trip and she is just more comfortable using the device that she uses all the time for other things.
