I think the 16C54 is still being made, but check with Microchip.  As an
OPT it is cheaper than the 16F628.  For production work
reprogrammability is usually not an issue.  It is not a "sexy" chip, but
if it has what you need the old war horse may do just fine.  Any decent
industrial chip burner can handle them.

If you are experimenting at home, or if you are altogether new to uC's
then the 16F628 may indeed be better.
