I am not sure you should. The "C" chips are more rugged, the EEPROM 
section actually
works without dropping bits, and the 'C's are less susceptible to EMI. 
Production cut?
It would kill a LOT of Microchip's income, so I doubt it will happen 
anytime soon.

Don't get me wrong. I love the convenience of the "F" parts, but 
Microchip's flash
implementation is not quite ready for prime time yet.

I use a DIY K150 to program PIC16C devices. They are assembled and sold 
in the USA
through amazon electronics, hobby engineering, and  Carl's electronics. 
About $50 with
a ZIF socket.
