DDPlan by Gordon Henderson (free software) has a table function where you can print-off different depths and times which are then laminated. This gives you the various permutations in a handy laminated slate(s). It also can produce bailout tables. Not as elegant as the VR3.
Warning: I dive D'OH rather than DIR and avoid caves wherever possible.
