Task Management

[SteveFil]

I need to find a relatively cheap (ie less than $100), simple task manager wich the following attributes:

Syncs to Palm
Has some categorization capability and prioritizations (LMH or 1-5)
Ability to attach files
Nice Mac interface
Integrates with Mail, Address and iCal for due dates

Any thoughts? I have tried DayLight (too complicated), iTask, Life Balance, Entourage (too outlook-y and non-Mac), Omni Outliner, ToDo (too simplied).
I have even tried managing an excel document, but you lose the "done" items too easily.

THANKS!
