1 GB or 2 GB Clip for audiobooks and podcasts?

Thank you all for weighing in.  I will go with the 2 GB Clip (unless I can get the 4 GB Clip from Sears - I don’t see the link, but I’m off to search Sears).

And I will look into replacing the car stereo, but as I said, I am having trouble finding a unit that includes a tape deck, and I still sometimes use tapes. 

But, meanwhile, what about this as another option: a small, portable speaker, such as the Altec Lansing iM207 Orbit-MP3 (http://www.amazon.com/Altec-Lansing-iM207-Orbit-MP3-Players/dp/B000YEKM0U/ref=cm\_cr\_pr\_pb\_t)?

Not only could I use it in the car, I might also be able to bike with it. (I would never wear headphones while biking.)
