Thank you all for the recommendations. They were very helpful. I looked hard at both the e200 series and the Clip. In the end the cheap minimalist in me decided to go with the 2GB Clip in black. It was just what I needed and nothing more, so I went for it.
I might have bought the 4GB Clip, but I really dislike the silver case and especially the silver faceplate. I know the OLEDs shine through, but I think there needs to be a display window to balance the controls. Plus, the 2GB Clip was cheap: $48 on Amazon. After I applied a $30 credit, it was only $18 out of pocket. That's probably cheaper than a replacement battery.
I'm looking forward to trying it out soon. Thanks again for your help!
