Sean,
   You have really hit the nail on the head
there.  If you just wan to hit the ground
running, then you can hit it with anything.  I
started out on Motorolla 68hc11's, and when I
switched to the PIC pretty much all the concepts
were the same, so if you are just intent on
learning the basics, then whatever you can find
is the way to go.  As far as actually moving code
between chips, I only have experience working
with the 18f series, but I have moved mountains
of code back and fourth between them without a
problem.  On top of that, Microchip seems to take
care that all of it's peripherals are standard
between chips, adding and removing them as
modules.  The information for the 30f series
supports that, with most of the configuration
informaiton being in the family refernce guide
instead of the individual chip datasheets, they
jsut show you how to configure any SPIx module,
and you just mkae sure that the chip you order
has the spi module.  I agree with the person who
suggested starting with the one that has the most
peripherals and only scaling it down when you get
to the productions stage, and microchips free
sample program means that even if you need 10
chips, between the low voltage and normal voltage
versions and being able to order once a month,
you can have enough chips to goof around wiht for
the price of none!  All the development for this
project:
http://engineering.lssu.edu/students/ROV03.html
was done with free sample 18f452's, and there
were a-lot of 18f452's in the dead bin when we
got done.  Buy Big (esp when it is free).
