I've got the Agent 18 clear hard case for my iPod w/ video and I like it. Since I have the 80GB it's already a little bulky as it is, a little, but the case doesn't add too much. And I know when it's in the case and I leave the house my iPod is gonna be pretty safe in it and won't get any scratches. The only thing is sometimes it's hard to watch video through it, since the case gets kinda scratched up and what not, so normally if I wanna watch video on it i'll pop the top portion of the case off, just while I'm holding the iPod and watching something. Otherwise, it's cool.
