For those of us who prefer "complicated" to expensive, a discrete
transistor voltage amplifier can be used to "boost" the output of a
regular op-amp up to high voltage.  A sample of the high-voltage output
is taken with a resistor divider and applied to the op-amp for feedback.
The values of the resistor divider (especially the resistor to ground)
could be adjusted by the PIC to get different full-scale voltage ranges.
