I listen to a lot of audiobooks and just did a search for some new sources and found a site that must have been there a while but it's new to me:

http://www.podiobooks.com

I sampled a few books and seems like some of the readers (all of the samples I listened to were the authors) are OK and some are, well, straight out of Ferris Bueller's science class...anyone....anyone...pretty much a droning mono-tone read.

One neat thing is the content seems free or at least you can donate is you enjoy a book. Plus the books are serialized with podcast feeds...could be a fun source of something different from other content options. The audio plays fine on my N800.

Not always great content but it's a reasonable model for business...like it and ya pay for it...don't like it, don't pay anything...or at least you can pay what you can afford.
