Has anyone tested DLO clip yet? they are a little bit more expensive ($20) than dvforce or extreme clips but available in an apple store near where I leave. So i save on shipping :)
The Lounge did a review. Click on the logo in the upper left, then "Reviews", then scroll down to the "Clips and Guards for iPod Shuffle." It's the second one down.
I personally like the XtremeMac SuperClip as it's light, doesn't add and thickness to the Shuffle and you don't have to remove it to charge/sync. It's $20 after shipping too.
