Yes I agree that 18F1320 is a very good alternative, but in replacement of
the 16F84, for BEGGINERS, I think that the best replacement is 16F628A
because it's software compatible. Most of the examples we find on the web
are written in 14bit assembly or in some freeware tools that produce only
code for 16Fxx series. The only difference in code between 16F628 and 16F84
is that we have to disable (One line of code) the analog comparators. All
other code will remain the same.
For 18Fxx the only tools I know that are free are C compiler (from
Microchip) and may be some limited version (in code) from Mikroelektronika.
But most examples written in assembly are for 14bits cores that needs to be
reviewed to work with 16bit core chips (mostly becauseof abs jumps).
This is wy I say:
If you need a replacement for the 16F84 use 16F628A
If you want only to start playing with PIC go directly to 18Fxxxx.

If you are switching, why not try the PIC18F1320. 18 pins, faster, more
memory,
infinitely better stack, multiple memory pointers. I switched a couple
years with
no regrets. I mostly use the 28 pin 18f252 (pin compatible with 16f876)
