Ok. Now take a look at Tait's programmer, and your HVP programmer. If you add
the 7805 and 7812, the 100nF capacitors, diodes to your HVP programmer you get
almost the same amount of components.
Just to add, I know the 'passive' programmer which gets power from the serial
line. As an engenear I do not like this kind of simple circuit. It's more safe
to hava a little more complicated, but more reliable stuff. But this is my own
philosofy.

I'm glad to hear that! Please share us your 18fxxx softwares and hardware
experiences!

I agree with that! I realised that PIC16F84 is the most expensive product of
Microchip! :-) It's busyness. Everyone see the '84 in the web, and run to the
first store and buy a few of it. So why would microchip push the price down?
