PNP photo transistors (OCP71) may not be available readily in the market. if you have patience you can make yours by modifying a standard PNP TO18 metal transistor BC177. just carefully file the top off, use alchohol and clean the jel inside, fit a small round plstic cap and seal it with anabond. i use this in all my opto projects. (BC107 for NPN and BC177 for PNP). with a small modification you can use the standard LDRs freely available in this circuit.
