I've had a bunch of cases up through my Palm 3xe, all those models were about the same size. I had a waterproof see-through/work-through case with a belt clip I used for sailing, it was by "Aquapak", but I think they quit making it- you see the same sort of thing for cell phones. There is one of the Otter boxes that's a very good fit up through the 3 series (coincidence, I think), bombproof, a bit bulky, no belt clip- but I went through the edges of hurricane Fran in a tent with it, and was very glad I had it along. Bought both the Otter and Aquapak from www.cases4less.com, which has very good prices on Pelican as well.<br><br>My all-around favorite was a Devian leather case that rode horizontally on the belt.<br><br>>>Perhaps it would be worthwhile, with so many Palm carriers here, to figure out the ultimate way to combine a carrying case with a PSK... <<<br><br>Hmm... the Devian case mentioned above has space on it's belt loop below the belt (horizontal carry), so I have been known to carry a small lockblade clipped there, behind the case- usually a CRKT Sampson's KISS (the larger kind). Out of sight, but very accessible. It's a start...<br><br>
