Good case for P7700 that goes on belt?

Hi guys,

Can anyone recommend a good but small case for the P7700 that can be put on your belt? I need room for a spare battery also, so it needs a flexible outside pocket.

The best I have found so far is the Lowepro Newport 30 (5.6 inches high). It works but just barely. I like the Newport 30 size - (I don't want a huge box on my belt like the Rezo 60) - but I would like something that is perhaps 1/4-1/2 inch taller/longer to make it a little less snug, but I don't seem to be able to find one anywhere.

Any suggestions?

Thanks!
