Dealmac: Monster’s new iSportCase costs $19.95 plus $4 shipping at The Apple Store. (To find it, search for “iSportCase”.) It’s the lowest total price we’ve seen.
This slim, open-face iPod case works like a cell phone belt clip to carry your iPod on your belt or the included self-adhesive car mount. There are two versions, for 10/15/20GB iPods and for 40GB iPods.
