I'd like one too, but think about what you're asking for!
The camera doesn't have a video card in it so you have 2 choices - 1) use the "video" out from the camera to a cheap LCD monitor that takes composite video in (to make "critical" decisions on
) or 2) download the file into a device that has RAM to hold the file, a video card to display it and a display to view it on (oops, that's a laptop, sorry!)
I'm a Mac guy so I second BJL's thoughts (G4 12"iBook drool...). The Fujitsu Lifebook Michael used on his Costa Rica trip looks good for a PC person.
Michael, I don't think what you are looking for exists, let alone at the price you want to pay!!!
