Can anyone recommend a good iphone case/holster?

I have the griffen case/holster right now... I dont really like it. Anyone have a recommendation for a case and holster combo for the iphone? Please include a link if you have one.

I have this one:

I really really like it. I'm not one to strap my phone to my belt, I like to keep it in my pocket, so this is perfect. Great protection, without too much added bulk. It is vented at the bottom for the speaker/mic and is open at top for access to the sleep/wake key and headphone jack. I picked it up at my local AT&T store for $19. I'm very happy with it. I will be adding some sort of screen protector as well though, Apple sells a nice set of two for $15.
