I'm ready for an mp3 player upgrade and was thinking of spending more and getting one of the new units that has picture replay / storage feature. The ideal would be something that could read and store my D50's SD card (directly without involving a laptop). Could then pass it around at shooting events and keep my camera in action and safe from handling. I've been reading some reviews and have not found a consensus yet. Not really interested in putting video on the device but would like a 2 or 3 inch 320x480 screen. Those with built in hard disks are getting down right cheap gut I really don't need that much capacity or fragility. Your thoughts appreciated !
