Hey, thanks for the suggestions. Not sure if the Peilfama case they show is what I was thinking, but it I could probably get a belt clip added and oriented the way I want it and it'd look good with business casual attire. So, that's definitely an option.
I also like the one that's on ThePouch.com. But, I think I might still go with the Scout for now. I really liked the Basecamp, so I'm sure I'll be happy with the Scout.
If the Basecamp fit my iPaq H3635 with CF sleeve and my Clie NX-60, I'm almost 100% positive it'll fit a C series Zaurus. One of the other drawbacks to the Basecamp, though, was I thought it was a little difficult to insert and remove a large PDA. I know the flap was designed to be secure, so that probably works out well for what it was designed for. I think for the C760, I'd prefer the Expedition and Scout depending on what activity I was up to and how many things I needed to carry.
I also talked to my girlfriend and described what I wanted. We think we could whip something up for about $10 and it'd only take a few hours. I'll probably want 2 or 3 cases to use for different occassions anyway. Besides, women get to have N-number of purses to match their dresses and outfits, why can't us geeks have N-number of cases for our geek accessories???
