Well, this stuff is so much a matter of taste...

but my personal solution is to use an oversize vertical cellphone beltclip case, carrying the otherwise unsheathed unit -- which makes it much easier to put it in my (freshly acquired) car mount.

The car mount is from Radio Shack -- that photo doesn't do it justice; it's quite nice, and has hollow end-arms so you can plug in power and audio while it's in the mount -- if your car has a shallower windshield than mine, you might need their other model with the long gooseneck.

The belt holster doesn't appear to be on Home Despot's website anymore; the relentless march of miniaturization has reduced the market for "large" cellphone holsters, but I *think* this one might be big enough. I previously had one large enough to also carry my irxon BT keyboard, but while that was a Pretty Neat *sounding* Idea, in practice it made the unit enough harder to get out of the holster that I've given up on it.
