I am trying to develop a unit which:-

  * Runs on a 9V battery
  *Power is turned on by a float switch ... at which point it needs to:-
         Wait 1 second -
                 if still turned on ...
                    check the battery level
                          turn on a piezo buzzer for 10 seconds
                                  (pulsing if battery is low)
                         go into sleep/low power mode indefinitely
                                  (until float switch opens turning off =
the device)

I only have 16F8XX programming tools (Microchips ICD) available
   I know these are overkill but so is forking out heaps of $$ for only
needing to program 15 chips.

What is the best oscillator for low low power consumption - I am thinking
RC. Obviously timing isn't critical - except for maybe the AD convertor.
