I have been looking for a low cost basic PDA and I was just at Target (TX) and picked up a Cassiopeia PV-S400 Plus-L with 4 mb memory for $49 plus tax. This was not a closeout but a price cut so it should be available in other areas. Best price I could find searching was $75. Used on Amazon are $59. Comes with cradle for automatically sync with Outlook.
