Yep, the first clip on generation shuffle is also an excellent choice. The battery in that little thing is astounding! I have had mine for years. I can actually leave it in a drawer for 2 or 3 months on end. Take it out and get an hour to an hour and a half of straight play time. Sound quality is ok, but like the previous poster said, it's no so much about sound as maybe motivating distraction.
I personally use the new nano clip on which I like just fine. I think it has very good sound quality for an ipod. Good power output. I really like it because it's so portable and the Nike + system is built in. The battery in it is horrid! In fact I think it gives off false readings when charging. I can charge it for a little over an hour from a completely dead unit, and the battery indicator says its got a full charge. I know that's not accurate, so I usually just keep it charging for a few hours.
